GC-MS identification of amine-solvent condensation products formed during analysis of drugs of abuse
Clark, C R; DeRuiter, J; Noggle, F T, Journal Of Chromatographic Science, 30(10), 399-404 (1992)

Abstract
The use of methanol or ethanol as the injection solvent for the gas chromatographic-mass spectral (GC-MS) analysis of low molecular weight amine drugs of abuse results in the formation of additional components in the sample. Primary amines, such as amphetamine, 3,4-methylenedioxyamphetamine, and phenethylamine, yield imines upon injection as methanol or ethanol solutions. In methanol, the imine formed has a mass that is 12 mass units higher than the parent compound. In ethanol, the products formed have 26 additional mass units. Secondary amines appear to undergo methylation under similar conditions with methanol as the injection solvent. These products are absent from the analysis of equivalent amine samples dissolved in chloroform.

Reaction Byproducts of Common Cold Tablet Ingredients Via Hydriodic Acid/Red Phosphorus
Oulton-S-R; Skinner-H-F, Microgram 32(10), 257-285 (1999)

Abstract
In southern California, the current method of choice for the synthesis of illicit methamphetamine is the reduction of ephedrine or pseudoephedrine with hydriodic acid and red phosphorus. However, as a result of restrictions on the availability of both precursors, common cold tablet preparations are increasingly being used as a source of ephedrine and pseudoephedrine. Such tablets also contain other ingredients such as paracetamol, chlorpheniramine, dextromethorphan, diphenhydramine, doxylamine, guaifenesin, and triprolidine. Depending on the isolation method used, these other compounds may be present in the reaction mixtures and subsequently produce other by-products. This paper describes the by-products formed as a result of the reaction between the tablet ingredients and hydriodic acid/red phosphorus. The identification of the by-products found in clandestine methamphetamine laboratories would help to determine the exact cold preparation used as the source of the precursor.

Could anyone fetch these two revolutionary articles by Channe Gowda, published back-to back in Ind. J. Chem?

Hydrazine/magnesium mediated cost-effective and selective reduction of nitro compounds
Srinivasa GR, Abiraj K, Gowda DC, Ind. J. Chem. Sect. B,  42(11), 2885-2887 (2003)

Abstract
Hydrazine aided catalytic transfer hydrogenation has been employed for the reduction of both aliphatic and aromatic nitro compounds to corresponding amines. The use of low-cost magnesium, as catalyst leads to high yields of amino compounds under ambient conditions of temperature and pressure. Many commonly encountered functional groups like ethene, nitrile, acid, phenol, halogen etc. are compatible with the present system.

Magnesium/ammonium formate promoted rapid, low-cost and selective reduction of nitro compounds
Srinivasa GR, Abiraj K, Gowda DC, Ind. J. Chem. Sect. B,  42(11), 2882-2884 (2003)

Abstract
The reduction of nitro compounds, both aliphatic and aromatic into corresponding amines has been achieved at room temperature in good yields by employing ammonium formate in the presence of low cost magnesium powder. The hydrogenation is fast and selective in the presence of other sensitive functionalities such as halogens, -OH, -OCH3, -CN, -COOR, -COOH etc. It was observed that, this system is equally compatible with existing methods, which employ expensive catalysts like palladium, platinum, ruthenium etc.

Catalyst selection for the lactonization of 1,4-butanediol
Srinivas B, Subrahmanyam M, Kulkarni SJ, Rao YVS, Rao AVR
Indian Journal Of Chemical Technology 3(4), 237-238 (1996)

Abstract
Chromite catalysts have been studied with and without modifiers for lactonization of 1,4-butanediol. The reaction on majority of the catalyst proceeds giving rise to cyclodehydration product, tetrahydrofuran (THF) mainly rather than cyclodehydrogenation product of gamma-butyrolactone (gamma-BL). The lactonization of 1,4-butanediol increases when the zinc chromite catalyst is modified with Pt metal. Few methods are discussed regarding the preparation and modification of the catalysts and their effects in selectivity from THF to gamma-BL.

Foxy, data from that dissertation about fluorinated tryptamines and thienopyrrolee has been published in J. Med. Chem. in two different papers a while ago. Search for the co-author D. E. Nichols. But both papers didn't look very promising. The fluorinated tryptamines were 5-HT1A selective if I remember correctly.

That looks like a patent application.  They publish them after 18 months now.  09/652,376 is an application number not a patent number.  Maybe it'll bee published in January.

Recent Synthetic Applications of Chiral Aziridines
Synthesis 1347-1365 (2000)

Due to their ready availability in chiral form, and propensity to undergo regio- and stereoselective ring opening, aziridines have found widespread use in asymmetric synthesis. This review attempts to summarise the breadth of use of chiral aziridines in synthesis that has recently been reported. Particular emphasis is put on the effect of substituents on ring openings, rearrangements and use as chiral ligands and auxiliaries.

      Ketone deoxygenation with NaBH4?     

In JOC 48, 4151 (1983), the following procedure is described:

"Thus, 2-hydroxy-3-Bromo-5-methoxybutyrophenone was first acetylated (5 eqv Ac2O/5 equiv 5% NaOH/ice/3 min) and then the crude acetate was treated with 4 eqv of NaBH4 (aqueous THF/15°C/1 h) to furnish 2-hydroxy-3-Bromo-5-methoxybutylbenzene in 92% yield."

The reference they give is Minami & Kijima, Chem. Pharm. Bull. 27, 816-820 and 1490-1494 (1979)

I have never before seen such a mild ketone deoxygenation, so I'm really curious what the original article says.

Abstract
The reaction of producing potassium tert-butoxide (I) from potash and tert-Bu alc. is an intensive reversible reaction.  Because the reaction equil. favors the formation of alc., I cannot be obtained without removing the water formed during the reaction.  So a technol. integrating azeotropic reaction distn. in boundary film and a packed column having large surface area is applied.  The potash conversion is greater than 93%.  It has obvious tech., economical and safety advantages over the traditional method of producing I from metallic K.

Abstract

Reimer-Tiemann reaction and a methoxylation through di-Me sulfate are employed for the prepn. of 2,5-dimethoxybenzaldehyde from p-methoxyphenol in this paper.  Comparing different phase transfer catalysts, it can be demonstrated that the PEG-10000 is the most favorable catalyst used in Reimer-Tiemann reaction.  The yield and quality are improved through the methoxylation of 2-hydroxy-5-methoxy-benzaldehyde in a buffer soln.  The diverse factors influencing the yield are examd.  Some explanations are given from theor. viewpoint.  The proper exptl. conditions are found and the overall yield reached 68%.

Isolation of beta-asarone, an antibacterial and anthelmintic compound, from Acorus calamus in South Africa
South African Journal of Botany 68, 31-35 (2002)
LJ McGaw, AK Jäger and J van Staden

The aromatic rhizomes of Acorus calamus L. are used extensively in traditional medicine worldwide. They reportedly relieve stomach cramps, dysentery and asthma, and are used as anthelmintics, insecticides, tonics and stimulants. Alcoholic rhizome extracts of A. calamus growing in KwaZulu-Natal, South Africa, were previously found to have anthelmintic and antibacterial activity. Using bioassay-guided fractionation, the phenylpropanoid b-asarone was isolated from the rhizome. This compound was shown to possess anthelmintic and antibacterial activity. It has previously been isolated from A. calamus, and a related species, A. gramineus. Different varieties of A. calamus exhibit different levels of b-asarone, with the diploid variety containing none of the compound. Mammalian toxicity and carcinogenicity of asarones has been demonstrated by other researchers, supporting the discouragement of the medicinal use of Acorus calamus by traditional healers in South Africa.

Abstract

A new and improved synthesis of potentially hypocholesterolemic (E)-2,4,5-R(MeO)2C6H2CH:CHMe [I, R = NO2, NH2] from eugenol is described.  This pathway also allows the prepn. of the 2-propenyl analogs.  Moreover, 5,6-dimethoxy-2-methylindole was also prepd. efficiently by this method.  b-Asarone and (Z)-I [R = NO2] were also prepd. and the isomer ratios in natural and synthetic samples of a-asarone and I [R = NO2] detd. by GC/MS.

Abstract

Reimer-Tiemann reaction and a methoxylation through di-Me sulfate are employed for the prepn. of 2,5-dimethoxybenzaldehyde from p-methoxyphenol in this paper.  Comparing different phase transfer catalysts, it can be demonstrated that the PEG-10000 is the most favorable catalyst used in Reimer-Tiemann reaction.  The yield and quality are improved through the methoxylation of 2-hydroxy-5-methoxy-benzaldehyde in a buffer soln.  The diverse factors influencing the yield are examd.  Some explanations are given from theor. viewpoint.  The proper exptl. conditions are found and the overall yield reached 68%.

Note on page 989 under Experimental Procedure



2,5-Dimethoxyacetophenone (II) -- It was prepared from dimethoxybenzene and acetyl chloride in the presence of anhyd. aluminium chloride according to the procedure described in literature5




Reference 5 is Ber. (1905), 789

Could you use chloroacetone in place of acetyl chloride to get 2,5-DimethoxyP2P?  There seems to be a contradiction here

Abstract

A series of 4'-substituted phenyl-4-piperidinylmethanol and benzoyl-4-piperidine derivs. was synthesized as potential novel serotonin 5-HT2A receptor ligands that can be radiolabeled for in vivo brain imaging.  Compds. were prepd. by alkylation of 4-substituted benzoyl-4-piperidine with an iodo- or fluoro-substituted phenylalkyl halide followed by redn. with sodium borohydride.  Potency of novel compds. was detd. by in vitro radioreceptor affinity assays selective for serotonin 5-HT2A receptors.  Potent compds. were further evaluated for selectivity at serotonin-2A vs. 2C, 6, and 7, as well as dopamine D2 and adrenergic a1 and a2 receptors.  The novel compd. (4-fluorophenyl)-(1-[2-(4-fluorophenyl)ethyl]piperidin-4-yl)methanol (I) was particularly promising with high 5-HT2A potency (Ki = 1.63 nM) and >300-fold selectivity over other 5-HT receptor types.

Rats were trained to discriminate injections of 5-methoxy.N,N-dimethyltryptamine (5-OMe DMT. 3.0 mg/kg), a hallucinogenic agent for which a serotonergic mechanism has been implicated. from sahine in a two-lever drug discrimination task. After reliable levels of accuracy (>85%) were attained, the ability of the 5-OMe DMT cue to generalize to 36 substituted phenylisopropylamines (or their optical isomers) was assessed. The results reveal that. in general, the challenge compounds could be differentiated into three broad categories: Those that produced 5-OMe DMT-appropriate responding (generalization), those that produced partial 5-OMe DMT.appropriate responding (partial generalization) and those that produced negligible 5-OMe DMT-appropriate responding. It is concluded that certain of the substituted phenylisopropylamines. unlike amphetamine itself, can produce effects in rats similar to those produced by the training dose of 5-OMe DMT. and that a serotonergic mechanism might be involved.
  
Discriminative stimulus properties of DOM and several molecular modifications
Richard A. Glennon, Richard Young and John A. Rosecrans
Pharmacology Biochemistry and Behavior Volume 16, Issue 4 , April 1982, Pages 553-556
DOI:10.1016/0091-3057(82)90413-0
 
Abstract:

Rats trained to discriminate racemic 2,5-dimethoxy-4-methylphenylisopropylamine, (±)-DOM (1.0 mg/kg), from saline in a two-lever drug discrimination task were challenged with the optical isomers of DOM as well as with several related agents which represent minor molecular modifications of the DOM structure. Generalization of the (±)-DOM stimulus was found to occur to R(-)-DOM, S(+)-DOM, (±)-2,5-dimethoxyphenylisopropylamine (2,5-DMA), R(-)-2,-5-DMA, and the 2-demethyl derivative of (±)-DOM. The 3-methyl positional isomer of (±)-DOM was found to produce only 34% DOM-appropriate responding at the highest dose tested while administration of S(+)-2,5-DMA and the 5-demethyl derivative of (±)-DOM resulted in disruption of behavior.

Abstract
Alkylation of deprotonated diphenylacetonitrile (2) with an acetal of chloroacetone followed by acidic hydrolysis and reductive amination of the resulting ketonitrile 12 offered an easy access to the methadone precursor 3. By this pathway the formation of the undesired regioisomer 4 was avoided.

This reference which discusses DXM would also be a very useful addition to the Levorphanol synth on Rhodium's by DopaMan, https://www.rhodium.ws/chemistry/levorphanol.html

The synth for this powerful opiate is very straightforward except for the difficulty in obtaining 2-(1,4-Cyclohexadienyl)ethylamine. This compound can be made from PEA (decarboxylate phenylalanine) with a controlled birch reduction of the ring, however the reference given here would seem to procede from cyclohexanone or cyclohexanol which would offer a far simpler route.

I can email the articles to the bees in question (assuming I'm provided with email addresses); however, if you'd be so kind Rhodiumsmile, I'd really appreciate it if I could email you all the above for hosting purposes, which would also make them available to all others who are interested.

A bonus article for anyone else having access to trifluoroacetic anhydride coupled with an unhealthy interest in Friedel Crafts acylations; the article in question having been referred to in both Post 406009 (Assholium: "пропиофеноны со всеми вытекающими", Russian HyperLab) and Post 403374 (bottleneck: "A 'regenerable' Friedel-Crafts acylation catalyst", Novel Discourse).

To stir up a little interest I should perhaps mention this is one of the few methods allowing the acylation of benzodioxole without causing significant demethyleneation/decomposition; therefore it could be rather useful for the synthesis of the otherwise elusive 3,4-methylenedioxypropiophenone, the only real hurdle in an otherwise facile preparation of that Holy Grail of cathinones, Methylone.

Experimental from JACS 75, 3004 (1953)

2,5-Dimethoxyphenethyl alcohol
n-Butyllithium was prepared from lithium (28g) and n-butyl chloride (180g) in dry ether (350 ml.). A solution of hydroquinone dimethyl ether (205g) in dry ether (776mL) was added in one portion and the solution allowed to stand for 15 hours. The reaction mixture was maintained at 0°C while ethylene oxide (130g) was passed in as a gas during 3 hours. After standing overnight the reaction mixture was poured into ice-water (2 liters). The organic layer was separated, dried and fractionated. There was obtained 182g (68%) of product, bp 130-142°C/0.7mmHg, n25D 1.5402.
This alcohol formed a p-nitrobenzoate which melted at 73-74°C. From the distillation residue (20g) 6g of a crystalline by-product, mp 134-135°C, was isolated.

2,5-Dimethoxyphenethyl Bromide
A solution of 2,5-Dimethoxyphenethyl alcohol (66g)  in benzene (65 ml) was stirred and cooled in an ice-bath while phosphorus tribromide (30g) in benzene (50 ml) was added dropwise. The solution was kept at 0-5°C for two hours and then at 60°C for four hours. Ice-water was added to the cool reaction mixture and the organic  layer was separated. The benzene solution of crude bromide was washed with ice-cold 5% sodium hydroxide solution, water and dilute hydrochloric acid. Acidification of the sodium hydroxide extract yielded about 20g of an oil containing phenolic by-products. The benzene solution was concentrated and the residual crude bromide distilled rather quickly at a low pressure and temperature. There was obtained 48g (54%) of 2,5-Dimethoxyphenethyl Bromide, bp 97-110°C/0.25mmHg, n24D 1.5542. There is decomposition of this bromide with distillation and in three separate attempts an analytically pure sample could not be prepared, some loss of hydrogen bromide took place even with evaporative distillation.

The synthesis and the spectroscopic data of 14 novel 4-substituted mescaline derivs. are reported.  Starting from syringaldehyde (4-hydroxy-3,5-dimethoxybenzaldehyde), several ethers were obtained from reaction with a series of corresponding satd. and unsatd. alkyl- and fluoroalkyl halides.  Henry-reaction with MeNO2 or EtNO2 followed to afford the nitro-olefins, which were then reduced with AlH3 to the desired 2-phenylethyl- and 1-methyl-2-phenylethylamine derivs.

Abstract
Reimer-Tiemann reaction and a methoxylation through di-Me sulfate are employed for the prepn. of 2,5-dimethoxybenzaldehyde from p-methoxyphenol in this paper.  Comparing different phase transfer catalysts, it can be demonstrated that the PEG-10000 is the most favorable catalyst used in Reimer-Tiemann reaction.  The yield and quality are improved through the methoxylation of 2-hydroxy-5-methoxy-benzaldehyde in a buffer soln.  The diverse factors influencing the yield are examd.  Some explanations are given from theor. viewpoint.  The proper exptl. conditions are found and the overall yield reached 68%.

A study on wastewater minimization in indirect electrochemical synthesis of benzaldehyde
Ding Zhou, Zhirong Sun and Wanli Hu

Department of Applied Chemistry, Harbin Institute of Technology Harbin, 15001 China

ABSTRACT:
Development of methods of pollution prevention is a strategic orientation for environmental protection. This paper describes studies on waste minimization in benzaldehyde production by using indirect electrochemical oxidation of toluene instead of the seriously polluting traditional chemical process. The new technology developed eliminates the discharge of wastewater by recycling the reactive solution and gives a higher yield of benzaldehyde

A new approach to electrochemical production of benzaldehyde from toluene in an undivided cell in the presence of the couple V5+/V4+
Qingfeng Y.1  Xiaoping L.2    and  Xiuling Z.2


Abstract:
 

Oxidation of toluene to benzaldehyde in the presence of the redox couple V5+/V4+ was carried out in an undivided cell where oxygen gas was continuously bubbled over the cathodic surface and the electrolyte was a mixture of aqueous H2SO4 solution containing V5+ and toluene. Some experimental conditions affecting the current efficiency for benzaldehyde production, such as H2SO4 concentration, current density, V5+ concentration and surfactants, were determined. The maximum current efficiency for benzaldehyde production at ambient temperature was 156.3% under the conditions of 11 M H2SO4, 2.7 Ч 10−4 M CTAB, current density 1.25 mA cm−2 and 0.0128 M V5+.

Abstract
Salvinorin A (1), a nonnitrogenous, neoclarodane diterpine, obtained from Salvia divinorum, has been reported to be the most potent naturally occurring hallucinogen, with an ED in humans in the 200-1000 µg range when smoked with a typical duration of action being several minutes to an hour.  Salvia divinorum exts. and salvinorin A have become widely used in the U.S. as legal hallucinogens.  The site of pharmacological activity remained a mystery until the recent report that identified salvinorin A as a potent and selective ligand for the κ-opioid receptor.  Thus representing a unique structural class of nonnitrogenous opioid ligands.  In order to investigate structure-activity relationships of salvinorin A, analogs must be made.  One approach to analog synthesis is from a total synthesis perspective.  To our knowledge, there are no known syntheses of salvinorin A. Here we report our progress toward the first total synthesis of salvinorin A.

Abstract

Long-term daily use of gamma-hydroxybutyrate (GHB) and related compounds has recently been associated with a withdrawal syndrome. To the best of the authors' knowledge, there are currently no animal models of GHB withdrawal. Objectives: The authors studied and described the effect of chronic dosing of GHB (3-6 days) on tolerance and withdrawal in a rat model. Methods: Rats were administered GHB every three hours via intraperitoneal catheter. Groups of rats (2 per group) were dosed with GHB for either 3 (24 doses), 4 (32 doses), 5 (40 doses), or 6 (48 doses) days. The GHB dose was 0.25 g/kg for doses 1-8, 0.75 g/kg for doses 9-12, 1 g/kg for doses 13-16, 1.25 g/kg for doses 17-24, 1.5 g/kg for doses 25-32, 1.75 g/kg for doses 33-40, and 2 g/kg for doses 41-48. Following the last dose of GHB, the rats were scored using a 16-point ethanol intoxication-withdrawal scale rating spontaneous behaviors, response to handling, grooming, and neurological signs. Lower scores indicate intoxication, while higher scores indicate withdrawal. Scores were recorded at hours 0, 1, 2, 3, 4, 5, 6, 9, 12, and 24. Results: Tolerance: Rats dosed with GHB for more days were less intoxicated one hour after their last GHB dose despite receiving higher doses. Withdrawal: The scores for all rats dosed with GHB increased at hours 4 (p = 0.028), 5 (p = 0.037), 6 (p = 0.007), and 9 (p = 0.024) after the last dose, indicating withdrawal. The scores demonstrated a linear increase dependent upon the number of days of GHB dosing at hours 3 (p < 0.000), 4 (p = 0.004), 5 (p = 0.002), and 12 (p = 0.039) as well as prior to the last dose at hour 0 (p = 0.000). No rats developed seizures. Conclusions: Tolerance and mild withdrawal in rats can be induced by administering intraperitoneal GHB every three hours for 3-6 days. More prolonged dosing and higher doses of GHB may be necessary to induce severe withdrawal.

      An easy one     

This should be quite easy, SWIM's library is missing the year!... Bull. soc. chim., pp.196, 1940

They claim to chloropropylate anisole, and dehydrohalogenate to get anethole. It might be applicable for 3,4-methylenedioxybenzene --> isosafrole. The paper also descibes 30% yield in chloroisobutylation of anisole and 40-60% yield for chloroethylation.

      the only ref. on MMA human use     

de Zorzi, C., Cavalli, A., Zacchia, 10, 3 (1974)

Journal info: Zacchia: archivio di medicina legale, sociale e criminologica
Roma, -, 1921-  *  Non pubbl. dal 1981 al 1982  *  ISSN 0044-1570

The experiments on animals suggest that MMA (3-methoxy-4-methylamphetamine) can be considered as a non-neurotoxic analog of MDMA (https://www.rhodium.ws/pdf/mmai.pdf)

A quote from PiHKAL #123: (http://www.erowid.org/library/books_online/pihkal/pihkal123.shtml)

Some years ago a report appeared in the forensic literature of Italy, of the seizure of a small semitransparent capsule containing 141 milligrams of a white powder that was stated to be a new hallucinogenic drug.  This was shown to contain an analogue of DOM, 3-methoxy-4-methylamphetamine, or MMA.  The Italian authorities made no mention of the net weight contained in each dosage unit, but it has been found that the active level of MMA in man is in the area of 40-60 milligrams.  The compound can apparently be quite dysphoric, and long lived.

There are several questions that may be answered in this article:
  • Are there anecdotal reports on the effects of MMA in humans?
  • How was the structure of the seized substance elucidated? Is there any possibility that it could be actually an isomer of MMA, say, 4-MeO-3-Me-A, PMMA, or 4-MeO-3,5-diMe-PEA?
  • What method was applied to synthesize the substance?

Abstract

The possibility of using aliph. alcs. as hydrogen donors for the catalytic transfer redn. of nitro group over MgO was examd.  Catalytic hydrogen transfer was found to be effective and selective for redn. of nitrobenzene, 4-nitrotoluene, 4-chloronitrobenzene, 4-nitro-m-xylene, b-nitrostyrene, 3-nitrobenzaldehyde, 1-nitropropane, and 1-nitrobutane.  Conversion of starting nitro compd. into desired product depended on the alc. used as a donor.  Adsorption of reactant and catalyst deactivation were studied by ESR.  New aspects of a role of one-electron donor sites in hydrogen transfer over MgO were demonstrated.

      Structure-activity of piracetam-like compounds     

2-Pyrrolidinone moiety is not critical for the cognition-enhancing activity of piracetam-like drugs
Serena Scapecchi, Cecilia Martellia, Carla Ghelardini, Luca Guandalini, Elisabetta Martini and Fulvio Gualtieria
Il Farmaco, 58(9), 715-722 (2003)
DOI:10.1016/S0014-827X(03)00111-3

Abstract
Following the indications of previous work, 2-pyrrolidinone moiety of piracetam and piracetam-like compounds has been opened to the corresponding amide derivatives. As found previously in the case of 1,4-diazabicyclo[4.3.0]nonan-9-one compounds, the cognition-enhancing activity of 2-pyrrolidinone compounds is maintained in most cases, suggesting that this moiety is not crucial for activity.

Abstract

beta-Chloromethylmescaline-HCl (I) [49557-34-8] (>40 mg/kg, i.p.) produced a twitch syndrome in mice characteristic of mescaline action.  I may cyclize in vivo to an aziridine sterically resembling the psychotomimetic alpha-methylmescaline.  However, N-(beta-chloroethyl)mescaline-HCl [15257-73-5], which may cyclize in vivo to an aziridine resembling the pharmacol. inactive N,N-dimethylmescaline, produced a periodic spasticity response qual. different from that due to I or mescaline.  alpha-Chloromethylphenethylamine-HCl [49557-36-0] produced no response, indicating that the mescaline-like effect of I was due to its trimethoxyphenyl substituent and not to its potential as an alkylating agent.  To synthesize I, 3,4,5-trimethoxybenzaldehyde [86-81-7] was condensed with diethyl malonate, and the product was hydrogenated over Pd/C and reacted with EtONO to form Et [2-oximino-3-(3,4,5-trimethoxyphenyl)]propionate [49557-37-1]; this was reduced to 3,4,5-trimethoxyphenylalaninol [49557-38-2], converted to the sulfate ester, and then to I.

Hi! smile

Does any of you have access to this italian journal? Farmaco, Ed. Sci

I wanna those 3 refs, authors are S. Pietra and G. Tacconi:

Farmaco, Ed. Sci 13 893 1958
Farmaco, Ed. Sci 14 854 1959
Farmaco, Ed. Sci 16 483 1961


Altough the abstract are detailed, the actual text would be better (but it is italian, damn frown).

They describe this route:

Indigo --nitric acid--> Isatin --?acetone/MEK?--> Isatylideneacetone --Pd/C, STP, hydroxylamine--> the oxime --Na, boiling PrOH--> AMT/AET

To make AMT from indigo this easily without even passing through indole stage should be further researched. wink

Abstract
Reimer-Tiemann reaction and a methoxylation through di-Me sulfate are employed for the prepn. of 2,5-dimethoxybenzaldehyde from p-methoxyphenol in this paper.  Comparing different phase transfer catalysts, it can be demonstrated that the PEG-10000 is the most favorable catalyst used in Reimer-Tiemann reaction.  The yield and quality are improved through the methoxylation of 2-hydroxy-5-methoxy-benzaldehyde in a buffer soln.  The diverse factors influencing the yield are examd.  Some explanations are given from theor. viewpoint.  The proper exptl. conditions are found and the overall yield reached 68%.

Flavour and Fragrance Journal  (1991),  6(2),  161-3.

Abstract
The compn. of the Z. cassumunar oil from Indonesia was examd. by gas chromatog. (GC) and GC-mass spectrometry.  A major part of the oil consists of monoterpenes with sabinene and terpinen-4-ol as main constituents.  Sesquiterpenes accounted for a small part of the oil with sesquiphellandrene being the principal constituent.  In addn. to these terpenes the oil contains a no. of phenylbutanoids.  The essential oil obtained by steam contained about 25% of these phenylbutanoids whereas, the oil obtained by extn. with light petroleum had about 46% with trans-1-(3,4-dimethoxyphenyl)but-1-ene, trans-1-(3,4-dimethoxyphenyl)butadiene and trans-4-(3,4-dimethoxyphenyl)but-3-ene-1-yl acetate as the main constituents.

      methamphetamine impurities     

GC-MS analysis of methamphetamine impurities: reactivity of (+)- or (-)-chloroephedrine and cis- or trans-1,2-dimethyl-3-phenylaziridine
Lekskulchai V, Carter K, Poklis A, Soine W
J. Anal. Toxicol. 24(7), 602-5 (2000)

S-(+)-Methamphetamine is frequently found as the only isomer in urine specimens from methamphetamine abuseres. Enantiomerically pure S-(+)-methamphetamine can be synthesized from ephedrine or pseudoephedrine via chloroephedrine intermediates. These intermediates are unstable and capable of cyclizing to form cis- and trans-1,2-dimethyl-3-phenyl aziridine. Studies were done to determine if these intermediates could be detected when using a common gas chromatographic-mass spectrometric analytical method (derivatization with heptafluorobutyric anhydride, HFBA) for toxicological screening of methamphetamine. Analysis of (+)- or (-)-chloroephedrine after extraction into hexane and derivatization with HFBA indicated that both pseudoephedrine and ephedrine were the major compounds detected. Direct derivatization of a hexane solution of cis-1,2-dimethyl-3-phenyl aziridine yielded only the derivatives of ephedrine and pseudoephedrine, indicating that the aziridine intermediate is responsible for the formation of the ephedrine or pseudoephedrine. These studies indicate that the aziridine intermediates would not be detected in methamphetamine samples following HFBA derivatization.

Abstract

Metabolites of methoxyphenamine (I)  [93-30-1] were examd. in the urine of healthy human volunteers. The metabolites were sepd. by gas liq. chromatog. and identified by comparison of their chromatog. and mass-spectrometric behaviors with those of authentic synthetic compds.  5-Hydroxy-2-methoxy-N-methylamphetamine  [61866-76-0], a metabolite previously identified by indirect methods, was conclusively identified by comparison with the now-available authentic synthetic material.  In addn., 3 new metabolites of methoxyphenamine were identified 5-hydroxy-2-methoxyamphetamine  [87835-15-2], 2-methoxyphenylacetone  [5211-62-1] and 5-hydroxy-2-methoxyphenylacetone  [87835-16-3].

Synthesis and serotonin receptor affinities of a series of enantiomers of a-methyltryptamines:  evidence for the binding conformation of tryptamines at serotonin 5-HT1B receptors.

Journal of Medicinal Chemistry  (1988),  31(7),  1406-12. (https://www.rhodium.ws/pdf/nichols/nichols-amt-enantiomers.pdf)

Abstract
(R)- And (S)-a-methyltryptamines I (R = H, 4-OMe, 5-OMe, 6-OMe, 4-OH, 5-OH) were prepd. by treating indoles with CH2:CMeNO2, oxidizing the 3-(2-nitropropyl)indoles to the 2-oxopropyl analogs, reductive amination with (R)- or (S)-PhCHMeNH2, and hydrogenolysis.  To probe structure-activity relationships of serotonin receptors, affinities of (R)- and (S)-I were then measured. at the 5-HT2 antagonist receptor subtype, with displacement of [3H]ketanserin, and were estd. at the 5-HT1B receptor, with displacement of [3H]serotonin, in rat frontal cortex homogenates.  Enantioselectivity at the receptor subtypes varied, depending on R.  (S)-I (R = 5-OH, 5-OMe) had higher affinity or was equipotent to the R enantiomer.  This selectivity at [3H]serotonin binding sites was reversed for I (R = 4-OH, 4-OMe) R did not enhance affinity over I (R = H).  These results can be explained, for the [3H]serotonin displacement data, if the binding conformation is one where the ethylamine side chain is trans and lysing in a plane perpendicular to the indole ring plane.

Abstract

A new and improved synthesis of potentially hypocholesterolemic (no data) (E)-2,4,5-R(MeO)2C6H2CH:CHMe [I, R = NO2, NH2] from eugenol is described.  This pathway also allows the prepn. of the 2-propenyl analogs.  Moreover, 5,6-dimethoxy-2-methylindole was also prepd. efficiently by this method.  b-Asarone and (Z)-I [R = NO2] were also prepd. and the isomer ratios in natural and synthetic samples of a-asarone and I [R = NO2] detd. by GC/MS.

DOI:10.1021/ol015819b



Abstract
Manganese dioxide is employed as an in situ oxidant for the one-pot conversion of alcohols into imines. In combination with polymersupported cyanoborohydride (PSCBH), a one-pot oxidation-imine formation-reduction sequence is reported. This procedure enables alcohols to be converted directly into both secondary and tertiary amines.

Synthesis of Aminomethyl Derivatives of 2-Hydroxy-5-methoxythiophenol
Zh. Org. Khim., 32, 1552-1554 (1996) (http://hyperlab.0catch.com/ZhOrgKh_1996_32_1552.djvu) (journal written in Russian).

Abstract
Reacting p-methoxyphenol with sulfur monochloride we obtained 2-hydroxy-5-methoxythio-phenol.The latter yields by Mannich reaction with formaldehyde and secondary amines aminomethyl derivatives of 2-hydroxy-5-methoxythiophenol.

An excerpt from the experimental part:


2-Hydroxy-5-methoxythiophenol (II). To a solution of purified 4-methoxyphenol (I) (30 g) in benzene (100 ml) was added freshly distilled sulfur monochloride (16.2 g) over the course of 45 min at 40-45 °C. The reaction mixture was heated in a water bath until evolution of HCl ceased. Zinc dust (100 g) was added at 5-10 °C to the product obtained, followed by slow dropwise addition of conc. hydrochloric acid (500 ml). Then the reaction mixture was stirred for 1 h and heated in a water bath for 5 h. The mixture was extracted with benzene and washed with water. After evaporation of benzene, the residue was distilled under reduced pressure. Yield 40%, m. p. 29-30 °C.

“The alpha-methyl group of amphetamine itself can be replaced by allyl, ethyl, or ethynyl groups of electron-donating character, without deleterious effects on centrally-mediated actions [1,2], but replacement by electron-withdrawing groups, such as cyano [3] or trifluoromethyl [4], abolishes amphetamine-like properties.”

Abstract
Metabolites of methoxyphenamine (I)  [93-30-1] were examd. in the urine of healthy human volunteers. The metabolites were sepd. by gas liq. chromatog. and identified by comparison of their chromatog. and mass-spectrometric behaviors with those of authentic synthetic compds.  5-Hydroxy-2-methoxy-N-methylamphetamine  [61866-76-0], a metabolite previously identified by indirect methods, was conclusively identified by comparison with the now-available authentic synthetic material.  In addn., 3 new metabolites of methoxyphenamine were identified 5-hydroxy-2-methoxyamphetamine  [87835-15-2], 2-methoxyphenylacetone  [5211-62-1] and 5-hydroxy-2-methoxyphenylacetone  [87835-16-3].

Directional lipophilic character in a series of psychotomimetic phenethylamine derivatives
Life Sciences Volume 21, Issue 4 , 15 August 1977, Pages 569-576

Abstract
Octanol-water partition coefficients (log P) were determined for a series of substituted psychotomimetic phenethylamine derivatives. A relationship was established between log P, steric bulk in the paraposition and the ability to stimulate serotonin (5-HT) receptors in an in vitro sheep umbilical artery preparation. It appears that Log P values and in vitro activity in this preparation may be useful in predicting hallucinogenic potency in man.

Abstract:Four members of a new class of psychotomimetic agents have been synthesized and evaluated in man. These compounds, which incorporate  beta-methoxy group onto a beta-phenylethylamine sidechain. arc the first reported psychotomimctics which are structural analogues of the neurotransmitter noradrenaline. These substances are more potent than the corresponding phenethylamines (lacking a beta-methoxy group) but less potent than the correspondingly substituted amphetamine derivatives.

ENGLISH SUMMARY:

Ana Serpler -- PIPERAZINE DERIVATED MANNICH BASES. NOTE II. NEW
DERIVATIVES OF 4-(BENZOIL-ETHYL)-1-BENZOIL PIPERAZINE

Following studies carried out by the author previously, some Mannich
bases were synthetized, disubstituted aromatic derivatives of piperazine. In these,
the benzyl radical was maintained, as a substituent in one of the nitrogen atoms,
while in the second nitrogen atom alkyl-aryl-cetone chains were grafted as
alkyl substituents, alkyl-oxy, alkenyl-oxy or bromide in the para position on the
aromatic nucleus.
Eight new components were obtained that have not been mentioned in the
literature before.
The conditions were established for the preparation and the necessary
qnantitative estimations were carriled out, as well as spectral analysis in the
infra-red range.


The rest is in Romanian, but understanding it shouldnt be a problem with some knowledge of Italian...

      Mg reduction of Nitro groups + amphetamine     

Could anyone fetch these two revolutionary articles by Channe Gowda, published back-to back in Ind. J. Chem?

Hydrazine/magnesium mediated cost-effective and selective reduction of nitro compounds
Srinivasa GR, Abiraj K, Gowda DC
Ind. J. Chem. Sect. B,  42(11), 2885-2887 (2003)

Abstract
Hydrazine aided catalytic transfer hydrogenation has been employed for the reduction of both aliphatic and aromatic nitro compounds to corresponding amines. The use of low-cost magnesium, as catalyst leads to high yields of amino compounds under ambient conditions of temperature and pressure. Many commonly encountered functional groups like ethene, nitrile, acid, phenol, halogen etc. are compatible with the present system.

Magnesium/ammonium formate promoted rapid, low-cost and selective reduction of nitro compounds
Srinivasa GR, Abiraj K, Gowda DC
Ind. J. Chem. Sect. B,  42(11), 2882-2884 (2003)

Abstract
The reduction of nitro compounds, both aliphatic and aromatic into corresponding amines has been achieved at room temperature in good yields by employing ammonium formate in the presence of low cost magnesium powder. The hydrogenation is fast and selective in the presence of other sensitive functionalities such as halogens, -OH, -OCH3, -CN, -COOR, -COOH etc. It was observed that, this system is equally compatible with existing methods, which employ expensive catalysts like palladium, platinum, ruthenium etc.

Improved pharmacological activity via pro-drug modification: comparative pharmacokinetics of sodium gamma-hydroxybutyrate and gamma-butyrolactone
Lettieri J, Fung H-L
Research Communications in Chemical Pathology and Pharmacology 1978, 22(1)107-118

Abstract
Although gamma-butyrolactone (GBL) rapidly converts to gamma-hydroxybutyrate (GHB) in vivo, the lactone gave significantly more prolonged hypnotic effects than GHB when equimolar doses were compared both parenterally and orally in rats. Plasma drug concentrations were higher after GBL administration through both routes, consistent with the observed differences in the pharmacological activity of these two compounds. Oral GBL was absorbed much faster than oral GHB, with the dual effects of decreasing potential first-pass metabolism and elevating plasma drug concentrations to the region where capacity-limited elimination is operative. Parenteral GBL produced a slower initial drug plasma clearance than parenteral GHB. In spite of the rapid metabolism of GBL to GHB, the apparent tissue distribution of these two compounds may be different.

Examination of the essential oil from the fruits of parsley

6(9), 15 (1972).
(journal written in Russian)


Abstract
   The essential oil obtained by steam distillation of crushed seeds of parsley at 2 atm pressure was separated into 2 fractions which were analysed by GC. The oil was shown to contain apiole (57.6%), myristicin (10.8%), allyltetramethoxybenzene (0.8%) and terpenes: α-pinene (9.1%), camphene (0.3%), sabinene (6.3%), α-terpinene (1.8%), limonene (3.1%), γ-terpinene (0.2%) and p-cymene (2.8%). The derivatives of phenols were characterized by oxidation into apiolaldehyde (m. p. 101-102 °C) and tetramethoxybenzoic (m. p. 85-86 °C) and myristicinic (m. p. 206-207 °C) acids.

   I pretty much disbelieve the whole article. The authors claim that they separated the essential oil of parsley into the "phenolic" fraction (myristicin, apiole, and allyltetramethoxybenzene) and the neutral fraction (various terpenes) by means of 5% solution of KOH as if there were phenolic hydroxyls in apiole etc. .

   The page number given for the other article (Khim. Farm. Zh. 6(8), 23 (1972)) is probably incorrect.

      GABA-B as anxiolytic/antidepressant target     

Genetic and pharmacological evidence of a role for GABA(B) receptors in the modulation of anxiety- and antidepressant-like behavior.
Mombereau C, Kaupmann K, Froestl W, Sansig G, van der Putten H, Cryan JF.
Neuropsychopharmacology 29(6), 1050-62 (2004)

    Although there is much evidence for a role of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) in the pathophysiology of anxiety and depression, the role of GABA(B) receptors in behavioral processes related to these disorders has not yet been fully established. GABA(B) receptors are G-protein-coupled receptors, which act as functional heterodimers made up of GABA(B(1)) and GABA(B(2)) subunits. Using recently generated GABA(B(1)) -/- mice, which lack functional GABA(B) receptors, and pharmacological tools we assessed the role of GABA(B) receptors in anxiety- and antidepressant-related behaviors. In the light-dark box, GABA(B(1)) -/- mice were more anxious than their wild-type littermates (less time spent in the light; reduced number of transitions). GABA(B(1)) -/- mice were also more anxious in the staircase test. Conversely, acute and chronic treatment with GS39783, a novel GABA(B) receptor positive modulator, decreased anxiety in the light-dark box and elevated zero maze tests for anxiety. On the other hand, GABA(B(1)) -/- mice had decreased immobility (antidepressant-like behavior) in the forced swim test (FST). These behavioral effects are unrelated to alterations in locomotor activity. In confirmation of the genetic data, acute and chronic treatment with CGP56433A, a selective GABA(B) receptor antagonist, also decreased immobility in the FST, whereas GS39783 did not alter this behavior. Taken together, these data suggest that positive modulation of the GABA(B) receptor may serve as a novel therapeutic strategy for the development of anxiolytics, whereas GABA(B) receptor antagonism may serve as a basis for the generation of novel antidepressants.

Farmacologia della 3-fenilazetidina e di alcuni suoi derivati
G. Bianchi, G. Maffii
Il Farmaco, Ed. Sci.

Article in Italian. 473 kB (w/pictures).
Summary.
   The pharmacological properties (adrenergic) of substituted 3-phenylazetidines have been studied. 3-Phenylazetidine (L 2051) shows both excitatory and inhibitory effects on the β-sympathetic receptors: in small doses it produces increase in heart rate and contractile force; this effect is antagonized by dichloroisopropylarterenol. In high doses the drug reduces the effects of isopropylarterenol, and inhibits the inotropic action of epinephrine and arterenol. A biphasic action of L 2051 may be demonstrated also on the site of the α-receptors. The pharmacological activity of L 2051 may depend, at least in part, on histamine liberation. These various activities of L 2051 were found isolated in some of its derivatives.
   There is no synthetic part in the article. The derivatives of 3-phenylazetidine were synthesized according to the following publications:
Liebigs Ann. Chem., 626, 114 (1959);
ibid., 639, 157 (1961);

      J.Org.Chem. from 1970 doesn't look like a rare     

J.Org.Chem. from 1970 doesn't look like a rare object in todays libraries.

If you live in a city that has a university (where chemistry is taught) find out how to gain access to the university library, some require you to be an actual student, some just want you to pay the membership fee, some let anyone in for free.

If the university library is no option, then just let it be custom ordered from your local library, they can get you whatever you want, sometimes from the other side of the globe. To accomplish that, it would be helpful to know what that reference you've got laying in front of you actually says:

"Chlorination of aromatic systems with trichloroisocyanuric acid under polar and free-radical conditions" that's the title of the article, obviously.
Eric C. Juenge, D. A. Beal, W. P. Duncan these are the authors, yeah - right.
J. Org. Chem. translates into "Journal of Organic Chemistry" you can find lots of common abbr. here:
1970 year of publication
35(3)Volume(Issue)
719-722 pages

When you want the article custom ordered you probably need all of the above. If you want to find out, which library near you has the journal you use an OPAC like this one: http://catnyp.nypl.org/ . Then you'd only be searching for the title "Journal of Organic Chemistry" , you'll be presented with a list of libraries that carry it. Get in touch with one of them, making sure they've got the volume (year of publication) you want.

Then there's online document delivery services, I know some German ones but suppose you're not German, so you'll have to find out for yourself. http://www.lindahall.org is an US based science library, they've got nearly everything also the uncommon stuff even most well lead university libraries don't have. They deliver by e.mail if you want, but they're ridiculously expensive, find a better one.

Well, that said, your best bet is still to take a walk to your local library and ask the staff how to get the article in question, they will certainly be able to serve your request. Libraries kick ass !

Abstract
The possible relationship between metabolism and psychotomimetic activity among the methoxylated l-phenyl-2-aminopropanes led to our investigation of the in vitro O-demethylation of 1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane (1, DOM, STP). Employing a sensitive and highly selective stable isotope dilution assay, we observed that rabbit liver homogenates biotransform the amine 1 to its 2-O-demethyl, 5-O-demethyl, and bis(O-demethyl)metabolites. Both monophenolic metabolites are enriched in their S enantiomers. The bis(O-demethyl) metabolite has structural, chemical, and electrochemical similarities to the sympatholytic agent "6-hydroxydopamine". The possible significance of metabolic O-demethylation in terms of the psychotomimetic properties of amine 1 is discussed.

Reaction Byproducts of Common Cold Tablet Ingredients Via Hydriodic Acid/Red Phosphorus
Oulton-S-R; Skinner-H-F
Microgram 32(10), 257-285 (1999)

Abstract
In southern California, the current method of choice for the synthesis of illicit methamphetamine is the reduction of ephedrine or pseudoephedrine with hydriodic acid and red phosphorus. However, as a result of restrictions on the availability of both precursors, common cold tablet preparations are increasingly being used as a source of ephedrine and pseudoephedrine. Such tablets also contain other ingredients such as paracetamol, chlorpheniramine, dextromethorphan, diphenhydramine, doxylamine, guaifenesin, and triprolidine. Depending on the isolation method used, these other compounds may be present in the reaction mixtures and subsequently produce other by-products. This paper describes the by-products formed as a result of the reaction between the tablet ingredients and hydriodic acid/red phosphorus. The identification of the by-products found in clandestine methamphetamine laboratories would help to determine the exact cold preparation used as the source of the precursor.

The Identification of Cathinone in Khat (Catha edulis): A Time Study
Lee MM
J. Forensic. Sci. 40(1), 116-121 (1995)

Abstract
Previous studies on the khat plant (Catha edulis) illustrated the importance of using freshly harvested young shoots and leaves such that cathinone, the principal active component and Schedule I controlled drug contained within the plant, could be suitably isolated and identified. Upon drying and storage of the cut plant material, cathinone readily converts to the reduced product, cathine, which necessitates rapid extraction and chemical analysis for cathinone identification. This study demonstrates that by air drying the young khat shoots at ambient temperature, cathinone may be detected in khat samples that have been harvested for more than 10 days. Refrigeration for two weeks and freezing for one month of the khat samples also yield identifiable levels of cathinone. Cathinone and cathine are both specifically determined and differentiated by vapor phase infrared detection, which is the method of choice in relation to mass spectrometry.

Synthesis of monodisperse Au, Pt, Pd, Ru and Ir nanoparticles in ethylene glycol
 
Nanostructured Materials   November 1999, vol. 11, no. 8,   pp. 1277-1284(8)

Abstract:

Au, Pt, Pd, Ru and Ir nanoparticles with a narrow size distribution have been synthesized by chemical reduction of their corresponding metal species in ethylene glycol. In all cases, the average particle size was found to be smaller than 10 nm. Particle size was mainly controlled by varying the initial total metal concentration, the reaction temperature, and the concentration of PVP. With the exception of Ir, metal particle agglomeration and sintering was prevented by the addition of PVP, a well known protective agent that also aids particle dispersion.

J. Med. Chem. 42, 2993-3000 (1999)



Abstract
A structure-based search and screen of our compound library identified N-(2-phenoxyethyl)-4-benzylpiperidine (8) as a novel N-methyl-D-aspartate (NMDA) receptor antagonist that has high selectivity for the NR1/2B subunit combination (IC50 = 0.63 µM). We report on the optimization of this lead compound in terms of potency, side effect liability, and in vivo activity. Potency was assayed by electrical recordings in Xenopus oocytes expressing cloned rat NMDA receptors. Side effect liability was assessed by measuring affinity for 1-adrenergic receptors and inhibition of neuronal K+ channels. Central bioavailability was gauged indirectly by determining anticonvulsant activity in a mouse maximal electroshock (MES) assay. Making progressive modifications to 8, a hydroxyl substituent on the phenyl ring para to the oxyethyl tether (10a) resulted in a ~25-fold increase in NR1A/2B potency (IC50 = 0.025 µM). p-Methyl substitution on the benzyl ring (10b) produced a ~3-fold increase in MES activity (ED50 = 0.7 mg/kg iv). Introduction of a second hydroxyl group into the C-4 position on the piperidine ring (10e) resulted in a substantial decrease in affinity for 1 receptors and reduction in inhibition of K+ channels with only a modest decrease in NR1A/2B and MES potencies. Among the compounds described, 10e (4-hydroxy-N-[2-(4-hydroxyphenoxy)ethyl]-4-(4-methylbenzyl)piperidine, Co 101244/PD 174494) had the optimum pharmacological profile and was selected for further biological evaluation.

Novel IKK inhibitors: beta-carbolines.
Castro AC, Dang LC, Soucy F, Grenier L, Mazdiyasni H, Hottelet M, Parent L, Pien C, Palombella V, Adams J.
Bioorg Med Chem Lett. 2003 Jul 21;13(14):2419-22.

Inhibitors of IkappaB kinase (IKK) have long been sought as specific regulators of NF-kappaB. A screening effort of the endogenous IKK complex allowed us to identify 5-bromo-6-methoxy-beta-carboline as a nonspecific IKK inhibitor. Optimization of this beta-carboline natural product derivative resulted in a novel class of selective IKK inhibitors with IC(50)s in the nanomolar range. In addition, we show that one of these beta-carboline analogues inhibits the phosphorylation of IkappaBalpha and subsequent activation of NF-kappaB in whole cells, as well as blocking TNF-alpha release in LPS-challenged mice.

Abstract
Reductive amination is an important tool for synthetic organic chemists in the construction of carbon-nitrogen bonds. This reaction, also termed reductive alkylation, involves condensation of an aldehyde or ketone with an amine in the presence of a reducing agent. A wide variety of substrates can be used including aliphatic and aromatic aldehydes and ketones, and even benzophenones. A range of amines from ammonia to aromatic amines, including those with electron-withdrawing substituents, can be employed. For particularly sluggish reactions, such as those involving weakly electrophilic carbonyl groups, poorly nucleophilic amines, or sterically congested reactive centers, additives such as molecular sieves or Lewis acids are often useful.


This chapter focuses on those conditions in which the carbonyl component, amine, and reducing reagent react in the same vessel. This review is restricted to reductive aminations using borohydride and borane reducing agents. This chapter concentrates on reductive amination chemistry mediated by borohydride and other boron-containing reducing agents from 1971, the year when sodium cyanoborohydride was introduced, through the middle of 1999. In addition to reductive aminations of aldehyde and ketone substrates, reactions of related structures including acetals, aminals, ketals, carboxylic acids, nitriles, and dicarbonyls that form a nitrogen-containing ring are reviewed. Intramolecular processes in which the substrate contains both the carbonyl and amine moieties are described. The intramolecular variant is a useful method for preparing cyclic amines. All of the various boron-containing hydride sources in reductive aminations, including labeled metal hydrides, are reviewed. Instances of reductive aminations that failed are described. Applications of this method to a solid support in parallel synthesis in combinatorial chemistry as well as reductive aminations that proceed in tandem with a second reaction such as reductive lactamizations are discussed.


1. Introduction

Reductive amination is an important tool for synthetic organic chemists in the construction of carbon-nitrogen bonds. This reaction, also termed reductive alkylation, involves condensation of an aldehyde or ketone with an amine in the presence of a reducing agent as illustrated in Eq. 1. A wide variety of substrates

can be used including aliphatic aldehydes and ketones, aromatic aldehydes and ketones, and even benzophenones. Further, a range of amines from ammonia to aromatic amines, including those with electron-withdrawing substituents, can be employed. For particularly sluggish reactions, such as those involving weakly electrophilic carbonyl groups, poorly nucleophilic amines, or sterically congested reactive centers, additives such as molecular sieves or Lewis acids are often useful.

Reductive aminations have been reviewed on numerous occasions, (1-17) and this chapter focuses on those conditions in which the carbonyl component, amine, and reducing agent react in the same vessel. The reduction of a preformed, isolated species such as an imine or oxime is not covered. This review is also restricted to reductive aminations using borohydride and borane reducing agents. Reactions carried out with other metal hydrides or inorganic reducing agents in addition to catalytic hydrogenations, Leuckart conditions, and enzymatic reductive aminations are not included. A review summarizing reductive alkylation of proteins has been published recently, (18) and these substrates are not covered here. This chapter concentrates on reductive amination chemistry mediated by borohydride and other boron-containing reducing agents from 1971, the year when sodium cyanoborohydride was introduced by Borch and coworkers, (19) through the middle of 1999. Although we have been as inclusive as possible, there are almost certainly additional references that we inadvertently missed. We apologize in advance to those authors who do not see their own contributions cited here.

In addition to reductive aminations of aldehyde and ketone substrates, we review reactions of related structures including acetals, aminals, ketals, carboxylic acids, and nitriles as well as dicarbonyl substrates that form a nitrogen-containing ring. Intramolecular processes in which the substrate contains both the carbonyl and amine moieties are described. In these reactions, one of the components is typically masked, and reductive amination occurs upon deprotection. The intramolecular variant is a useful method for preparing cyclic amines.

While sodium cyanoborohydride is the best known hydride reagent for reductive alkylations, sodium borohydride is often used as well. (20) Sodium triacetoxyborohydride is now widely used because it is nontoxic and generally does not reduce the carbonyl group prior to imine formation. (21) Amine boranes such as borane-pyridine are also employed in reductive aminations. (22) We review all of the various boron-containing hydride sources in reductive aminations in this chapter, including labeled metal hydrides such as sodium cyanoborodeuteride.

Instances where reductive aminations fail are described, including cases when reaction is not observed and also where side products appear, such as alcohols and bis-alkylated amines.

Finally, we discuss the application of this method to a solid support in parallel synthesis and combinatorial chemistry as well as reductive aminations that proceed in tandem with a second reaction such as in reductive lactamizations.

The Tabular Survey at the end of the chapter includes thousands of specific reactions and applications for reductive aminations, including sections on aldehydes, ketones, dicarbonyl substrates, tricarbonyl substrates, carboxylic acids, nitriles, intramolecular reductive aminations, reductive lactamizations, and Michael-type additions and reductive aminations.

Abstract
An ideal oxidant should be highly reactive, selective, and environmentally benign. It should transform a broad range of substrates with diverse functional groups, preferably under catalytic conditions, and be readily generated from commercially available and economical starting materials. Of course, such an ideal oxidant has not yet been invented; however, the dioxiranes, which have risen to prominence during the past few decades, appear to fulfill these requirements in many respects. These three membered ring cyclic peroxides are very efficient in oxygen transfer, yet very mild toward the substrate and product. They exhibit chemo-, regio-, diastereo-, and enantioselectivities, act catalytically, and can be readily prepared from a suitable ketone (for example, acetone) and potassium monoperoxysulfate ( 2KHSO5 · K2SO4 · Caroate®, Oxone®, or Curox®), which are low-cost commercial bulk chemicals. Throughout the text KHSO5 is used to specify this oxygen source, rather than refer to one of the commercial trade names.


Isolated dioxiranes (as solutions in the parent ketones) perform oxidation under strictly neutral conditions so that many elusive oxyfunctionalized products have been successfully prepared in this way for the first time. Epoxidations, heteroatom oxidations, and X-H insertions constitute the most investigated oxidations by dioxiranes. An overview of these transformations is displayed in a rosette scheme. These preparatively useful oxidations have been extensively reviewed during the last decade in view of their importance in synthetic chemistry.

This chapter deals mainly with the epoxidation of carbon-carbon double bonds [ bonds in simple alkenes and with these electron donors (ED), electron acceptors (EA), and with both ED and EA] with either isolated or in situ generated dioxiranes. In view of the vast amount of material on alkene oxidation, the epoxidation of the double bonds in cumulenes (allenes, acetylenes) and arenes is covered in a separate chapter, together with the oxidation of heteroatom functionalities (nonbonding electron pairs), X-H insertions ( bonds) and transition-metal complexes.

Abstract
Five indolealkylamines (N,N-dimethyltryptamine, N-methyltryptamine, bufotenine, O-methylbufotenine, N,N,N-trimethyltryptamine iodide) were labeled with 11C by use of 11CH3I. The labeled compounds were synthesized with a radiochemical yield of 2-50% (based on trapped 11CH3I) in 20-35 min with radiochemical purities of more than 92%. The tissue distributions of these labeled compounds were investigated in rats. In all cases, the accumulations in the liver, lung and small intestine were high. [11C]DMT and [11C]OMB also accumulated to a large extent in the brain, where their accumulation was retained. Brain uptake of three other radiopharmaceuticals was low. [11C]DMT is the radiopharmaceutical of choice for the study of the serotonin action mechanism in the brain, because it has the highest radiochemical yield and the highest brain uptake of these 11C-labeled compounds.

Sigma compounds derived from phencyclidine: identification of PRE-084, a new, selective sigma ligand
TP Su, XZ Wu, EJ Cone, K Shukla, TM Gund, AL Dodge and DW Parish
J. Pharmacol. Exp. Ther. 259(2), 543-550 (1991)

Abstract
A series of compounds derived from phencyclidine (PCP) was examined in the sigma receptor and PCP receptor binding assays. The derivatives included compounds containing methylene, ethylene or carboxyl ethylene insertion between the cycloalkyl ring and the amine group of PCP. Various phenyl substitutions, cycloalkyl rings and amines of these derivatives were also examined. The methylene and ethylene insertions decreased the compounds' potencies at PCP receptors, whereas they increased the potencies at sigma receptors. The carboxyl ethylene insertion produced compounds with negligible potencies at PCP receptors while possessing high potencies for sigma receptors. One derivative (PRE-084; 2-(4-morpholino)ethyl 1-phenylcyclohexane-1-carboxylate hydrochloride) had an IC50 of 44 nM in the sigma receptor assay, an IC50 of more than 100,000 nM for PCP receptors and an IC50 higher than 10,000 nM in a variety of other receptor systems. In general, compounds with hydroxy-substituted phenyl groups tended to have decreased potency at sigma receptors, whereas methylphenyl and chlorophenyl substitutions increased potencies. Reduction of cycloalkyl ring size decreased potencies for sigma receptors and quaternized amine groups invariably lowered the compound's potencies. Conformational analysis indicated that PRE-084 fitted onto a pharmacophore model for the sigma ligands. The study describes a new, highly selective ligand for the sigma receptor. The results of this study also confirm distinctly different structural requirements for binding to sigma and PCP receptors and provide a new structural consideration for synthesizing sigma-selective compounds.

The Biochemical Bases of Psychoses (or; the Serotonin Hypothesis about Mental Diseases)
D.W. Woolley

comment first. not sure what you want to know, longimanus, and the comments on these two are a little scattered and short. so to sum up - 2-methyl-3-ethyl-5-nitroindole was given to humans in a single trial. these were hypertensive patients (number not stated) and in 10g/day oral doses they experienced "severe depression". studies on mice and dogs went well for a few months, but then a few of the mice began to freak out, and were very prone to noise-induced convulsions. there is a reference to another article by the author, which sadly gives absolutely no further details on the human research, except that it was not published.

medmain, where the above cpd. has its O's replaced with methyls, was not tested in man at the time of publication. this is because mice given 200mg/kg had violent seizures followed by temporary stupor. there isn't much else but some receptor studies.

Russ. Chem. Rev. 68(1), 73-84 (1999) (http://www.turpion.org/php/paper.phtml?journal_id=rc&paper_id=381)

Abstract
Data concerning the methods of synthesis, chemical transformations and application of levulinic acid are analysed and generalised. The wide synthetic potential of levulinic acid, particularly as a key compound in the synthesis of various heterocyclic systems, saturated and unsaturated ketones and diketones, difficultly accessible acids and other compounds is demonstrated. The accessibility of levulinic acid from hexose-containing wood-processing and agricultural wastes is noted. The bibliography includes 260 references.

Direct mono-N-alkylation of amines in ionic liquids: chemoselectivity and reactivity
(Cinzia Chiappe and Daniela Pieraccini, Green Chem., 2003, 5 (2), (193-197))

"A simple method for the N-alkylation of primary amines was developed using ionic liquids as solvent in order to prepare secondary amines selectively. In ionic liquids overalkylation of the initially produced secondary amines is in general markedly reduced. Various amines, alkyl halides and sulfonates were examined. The observed selectivities between mono- and dialkylation are typically on the order of 91, or higher. Only in the cases of allyl or benzyl bromides does the reaction give the corresponding tertiary amines exclusively. The relative nucleofugality of chloride, bromide, iodide and tosylate with several primary amines was also evaluated, as well as the effect of caesium hydroxide."




Aqueous N-alkylation of amines using alkyl halides: direct generation of tertiary amines under microwave irradiation
(Yuhong Ju and Rajender S. Varma; Green Chem., 2004, 6 (4), (219-221))

"Direct formation of tertiary amines viaN-alkylation of amines by alkyl halides occurs in aqueous media under microwave irradiation. This greener alternative is also a useful and powerful method to construct C–N bond without using any transition metal catalysts."

Abstract
A method for the alkylation of 3-unsubstituted indoles by means of 1-(ω-haloalkyl)pyridinium salts via the Friedel-Crafts reaction with the aid of complex catalysts, viz. complexes of zinc, tin and titanium chlorides with pyridine, was developed. On the basis of a study of the electronic spectra of the resulting 1-(3-indolylalkyl)pyridinium salts it was shown that they are molecular self-complexes. The stabilities of the molecular self-complexes were investigated as a function of the length of the alkyl chain and the character of the substituents in the indole ring.

Abstract
A series of benzotriazole derivatives were synthesized and tested in order to determine their activities for muscarinic receptor subtypes (M1, M2 and M3).Binding affinities were measured as K1 values by competition against <3H>-N-methylscopolamine in rat cortex, atria and ileum. Pharmacological in vitro tests were performed on isolated tissue preparations (rabbit vas deferens, guinea pig atria and ileum); the compounds showed antimuscarinic activity. The synthesized ligands were characterized by moderate activity; however, some of them displayed interesting selectivity profiles (M2/M1 and M2/M3); particularly, the selectivity exhibited by the benzotriazole derivative 14b was quite similar to that observed for AF-DX 116, a typical M2 specific antagonist.

Review: Reductions by the Alumino- and Borohydrides in Organic Synthesis, 2nd edition (by Jacqueline Seyden-Penne)
Hoye, R. C. J. Chem. Educ. 76, 33 (1999)

This book focuses entirely on the aluminohydride and borohydride reducing agents. It condenses a large body of information into a valuable user-friendly resource for synthetic organic chemists. The author states that "This second edition has been broadly updated, but it is no longer exhaustive. As in the previous edition, the examples are selected in order to cover problems that are frequently encountered in synthesis."

The first chapter (13 pages) gives an excellent summary of the approximately two dozen most widely used aluminohydride and borohydride reagents. Information is presented on the main applications of each reagent and its solubility characteristics, stability, and handling requirements. Cross-references are liberally given to subsequent chapters where more complete reactivity profiles and examples are found. Chapters two through five (155 pages) detail reduction of the main functional groups by these reagents.

Chapter two covers reductions of carbon-heteroatom single bonds (C-Hal, C-O, C-N, C-P). Reagents capable of effecting a desired single-bond cleavage are described, as are mechanistic considerations of the process. Chemoselectivity and regioselectivity are duly noted.

Chapter three is concerned with reduction of double bonds (C=C, C=O, C=N) and is by far the largest chapter in the book. Reduction of carbon-oxygen double bonds is organized by functional group. The examples for aldehydes and ketones illustrate the potential for selectivity in the presence of other functional groups; the control of stereoselectivity, including a discussion of the factors favoring the Felkin-Ahn or Houk models; a survey of enantioselective reducing agents, particularly those developed in recent years; and the influence of neighboring substituents on stereoselectivity as the result of chelation control. These concerns and further consideration of conditions for partial reduction are given for carboxylic acid derivatives. Similar examples are included for reduction of carbon-nitrogen double bonds.

Carbon-carbon and carbon-nitrogen triple bonds, both isolated and conjugated, are treated in Chapter four. The examples illustrate the potential for chemo-, regio-, and stereoselectivity. Chapter five addresses the reduction of "other derivatives", including nitro and nitroso derivatives, azides, organometallics, sulfides (sulfoxides, sulfones, and amine oxides), phosphine oxides and phosphates, silyl derivatives, and boron reagents. Seyden-Penne concludes with a large table (11 pages) that "shows at a glance" the various methods by which major functional groups can be obtained by hydride reduction with cross references to the appropriate sections of the text.

This book is a thorough and dense compilation of experimental results and observations that highlight selectivity at every level as well as experimental practicality. The 10-page index appears to be well organized and the referencing is extensive (more than 1000 references in 33 pages). Given the prevalent role of hydride reduction reactions in organic synthesis, many practitioners will want to have ready access to this book, and it is a must for all science libraries.

Review: Reductions by the Alumino- and Borohydrides in Organic Synthesis (by J. Seyden-Penne)
K. Smith, Appl. Organometal. Chem. 12, 881 (1998)

This book is an update from the first edition, which was published in 1991. In the first edition there was an attempt at comprehensive coverage of the topic, but in the second edition any such attempt has been forced to be abandoned. Nevertheless, this second edition is packed with information, cites around 1200 references, and provides a very useful source for anyone contemplating a complex hydride reduction.

The book is organized into five chapters, followed by 11 pages of synoptic tables, then the references and a subject index.

Chapter 1 introduces the most commonly used reagents, indicates their stability and solubility characteristics and briefly describes their main applications. Chapters 2–5 present the reduction of the main functional groups, with reference to features of selectivity and compatibility.
Chapter 2 deals with cleavage of carbon–heteroatom single bonds (halides, sulphonates, epoxides, alcohols, ethers, ammonium salts etc).
Chapter 3, the largest chapter with over 100 pages, deals with reduction of double bonds (other than C=C bonds). The bulk of the chapter (85 pages) concerns reductions of carbonyl compounds, including sections on different kinds of carbonyl compounds, asymmetric reductions and regioselectivity of the reduction of a,b-unsaturated derivatives. The chapter also covers imines, enamines, nitrogen heterocycles and oximes/hydrazones.
Chapter 4 deals with reduction of triple bonds and Chapter 5 with other derivatives (nitro compounds, azides, organometallics, and sulphur, phosphorus, silicon and boron compounds).

The entry point for many will be the synoptic tables. Here it is possible to look up a class of compound and choose a precursor substrate; the table will provide a list of reagents for the transformation and section references indicating where the reactions are discussed. The appropriate sections in Chapters 2–5 will provide the detailed discussion of those reactions and Chapter 1 will give an outline of the characteristics of the chosen reagent. Thus, the book is ideal for identifying the most useful references for any given reduction.

Because it is so densely packed with information, the text is somewhat difficult to read. This is almost unavoidable if the coverage is to remain so full and the book so short (220 pages), and the difficulty is easily outweighed by the value of the work as a source of reference and information.

This book is an imperative purchase for all chemical libraries and for any individuals who make regular use of complex hydride reductions.

A complete guide to selection and use of the best reagents for a wide range of transformations

This book is the updated and expanded Second Edition of Jacqueline Seyden-Penne's practical guide to selection of reducing reagents in organic synthesis. It is an indispensable working resource for organic synthetic chemists—the only reference focusing exclusively on aluminohydrides and borohydrides and their derivatives.

Simple to use, it is organized according to specific reductions so that chemists can more easily match the best reagent to a given transformation. Throughout, Dr. Seyden-Penne emphasizes four crucial categories: compatibility, possibilities for partial reduction, the regio- and stereoselectivity of reductions that are altered or controlled by neighboring groups, and asymmetric reductions.

Extremely well-referenced, Reductions by the Alumino- and Borohydrides in Organic Synthesis provides the most up-to-date, detailed coverage of:
  • Successful techniques for performing highly selective reductions
  • Chemo-, regio-, stereo-, and enantioselective reductions of both simple and complex compounds
  • Best methods for obtaining the main functional groups by hydridereduction, provided in quick-reference tabular form
  • New and more selective reagents developed within the last five years
  • Experimental conditions, including solvent and temperature, and yields for most cases described.

Improved pharmacological activity via pro-drug modification: comparative pharmacokinetics of sodium gamma-hydroxybutyrate and gamma-butyrolactone
Lettieri J, Fung H-L, Research Communications in Chemical Pathology and Pharmacology 22(1), 107-118 (1978)

Abstract
Although gamma-butyrolactone (GBL) rapidly converts to gamma-hydroxybutyrate (GHB) in vivo, the lactone gave significantly more prolonged hypnotic effects than GHB when equimolar doses were compared both parenterally and orally in rats. Plasma drug concentrations were higher after GBL administration through both routes, consistent with the observed differences in the pharmacological activity of these two compounds. Oral GBL was absorbed much faster than oral GHB, with the dual effects of decreasing potential first-pass metabolism and elevating plasma drug concentrations to the region where capacity-limited elimination is operative. Parenteral GBL produced a slower initial drug plasma clearance than parenteral GHB. In spite of the rapid metabolism of GBL to GHB, the apparent tissue distribution of these two compounds may be different.

The Cocaine Diastereoisomers
Allen AC, Cooper DA, Kiser WO, Cottrell RC
J. Forensic Sci. 26(1), 12-26 (1981)

Abstract
In the past, it has been argued in court, from a theoretical basis, that the techniques available to the forensic chemist would differentiate the “cocaines.” This work has moved that argument from the realm of the theoretical into that of experimental fact. The techniques of infrared spectroscopy (IR), nuclear magnetic resonance (NMR), and mass spectrometry (MS) will unequivocally identify the racemic cocaine diastereoisomer. In addition, this work shows that the enantiomeric form of cocaine can be assigned by crystal tests, IR, and melting point techniques. The pure enantiomers of allococaine and pseudoallococaine were not isolated. This does not create a problem because the techniques of NMR and MS, as performed in this study, will not differentiate enantiomers. Therefore, the logical sequence of first identifying the diastereoisomer (via IR, MNR, or MS) and then determining the chirality by crystal tests, IR, melting points, or optical rotation measurements is valid.

Identification of Some Chemical Analogues and Positional Isomers of Methaqualone
Dal Cason TA, Angelos SA, Washington O
J. Forensic Sci. 26(4), 793-833 (1981)

Abstract
The drug 2-methyl-3-ortho-tolyl-4-quinazolinone (methaqualone) and 15 chemical analogues and positional isomers were synthesized and identified by spectroscopic techniques. The series of analogues studied includes the compounds formed through substitution of hydrogen or halogen atoms in place of the methyl group of the 3-tolyl substituent in methaqualone. Additionally, the substituent's positional orientation of ortho, meta, or para is considered. Infrared, nuclear magnetic resonance, and mass spectra of the compounds are distinctive, and reference spectra are provided. Gas-liquid and thin-layer chromatographic systems for analysis of the compounds as well as melting point and ultraviolet data are discussed.

The Characterization of Some 3,4-Methylenedioxyphenylisopropylamine (MDA) Analogs
Dal Cason TA, J. Forensic Sci. 34, 928–961 (1989)

Abstract
The seizure in 1986 of a large-scale clandestine laboratory producing both the N-ethyl and the N,N-dimethyl analogs of 3,4-methylenedioxyphenylisopropylamine (3,4-methylenedioxyamphetamine [MDA]) and the recent identification of N-hydroxy MDA hydrochloride (HCl) indicate an interest by illegal laboratory operators in the synthesis of noncontrolled MDA analogs. Currently, identification of these new analogs may be hampered due to lack of available standards or reference data or both. This potential problem prompted the synthesis of the following N-substituted MDA analogs: N-methyl, N-ethyl, N-propyl, N-isopropyl, N-hydroxy, and N,N-dimethyl MDA. Each compound was prepared by reductive amination of 3,4-methylene-dioxyphenyl-2-propanone (MDP-2-P) using the appropriate amine hydrochloride and sodium cyanoborohydride. In addition, the acetyl derivatives of MDA, N-hydroxy MDA, and MDP-2-P oxime are reported. Spectral and chromatographic data are presented for each of the compounds synthesized.

Abstract
A fatality following ingestion of diazepam and 4,5-dihydro-4-methyl-5-phenyl-2-oxazolamine, a cyclic derivative of phenylpropanolamine known as U4EuH or 4-methyl aminorex, is described. Solid dosage samples of U4EuH were analyzed using gas chromatography, ultraviolet and infrared spectroscopy, nuclear magnetic resonance, and mass spectrometry. Physiological fluids were analyzed quantitatively by gas chromatography and qualitatively by gas chromatography-mass spectrometry. Concentrations of 4,5-dihydro-4-methyl-5-phenyl-2-oxazolamine were: in blood 21.3 mg/L; in urine 12.3 mg/L. Diazepam concentration in blood was 0.8 mg/L.

Methamphetamine synthesis via reductive alkylation hydrogenolysis of phenyl-2-propanone with N-benzylmethylamine
Harry F. Skinner, Forensic Sci. Int. 60(3), 155-162 (1993)
DOI:10.1016/0379-0738(93)90234-2



Abstract
Methamphetamine was synthesized by reductive alkylation hydrogenolysis of phenyl-2-propanone with N-benzylmethylamine. The expected product N-benzylmethamphetamine, once formed, undergoes hydrogenolysis to methamphetamine and toluene. The progress of the reaction, the intermediates formed during the reaction, and the products were analyzed by gas chromatography and mass spectrometry.

Spectral distinction between cis- and trans-4-methylaminorex
A. W. By , B. A. Dawson , B. A. Lodge and W-W. Sy, Forensic Sci. Int. 43(1), 83-91 (1989)
DOI:10.1016/0379-0738(89)90124-2



Abstract
The recent identification of the anorectic agent 4-methylaminorex (2-amino-4-methyl-5-phenyl-2-oxazoline) as a police exhibit in Canada led to the need to synthesize a reference standard specimen. Since this substance can occur as cis and trans isomers, both had to be prepared and characterized spectrally. cis-4-Methylaminorex was made from the erythro amino alcohol norephedrine (phenylpropanolamine), while the trans compound was made from the threo diastereoisomer norpseudoephedrine, in both cases by the treatment of the substrate with cyanogen bromide in a methanolic solution of sodium acetate. In this paper, the 13C- and 1H-NMR, infrared (IR), mass (MS) and ultraviolet (UV) spectra are reported, together with a commentary on the distinguishing features noted between the sets of spectra.

The reactivity of gamma-hydroxybutyric acid (GHB) and gamma-butyrolactone (GBL) in alcoholic solutions
Hennessy SA, Moane SM, McDermott SD, Journal of Forensic Sciences, Vol. 49(6), [10 pages] (2004)
DOI:10.1520/JFS2003340

Abstract
In this work the stability of GBL (gamma-butyrolactone) and GHB (gamma-hydroxybutyric acid) in alcoholic media was studied. Under acidic conditions the GBL will react with ethanol or methanol to give the corresponding ethyl and methyl esters of GHB. It can be seen that ester formation is dependent on the type of alcohol, the alcohol content of the solution, and the pH of the solution. Under the same conditions it was shown that GHB does not give rise directly to the corresponding ester when merely in the presence of an alcohol; however the ester will be formed if the conditions are present for conversion of GHB to GBL followed by subsequent reaction with alcohol. In alcoholic beverage samples spiked with GBL the expected conversion to GHB occurred, and the formation of the ethyl ester of GHB was also seen in some samples. Wine samples were analyzed for the presence of the ethyl ester of GHB, and the effect of adding GHB/GBL to hot beverages was studied.

High atomic yield bromine-less benzylic bromination
Ramon Mestres* and Jesús Palenzuela
Green Chemistry, 2002, 4, 314–316

A two-phase mixture (sodium bromide, aqueous hydrogen peroxide/carbon tetrachloride or chloroform) under visible light provides a simple and convenient system for benzylic bromination of toluenes. A high atomic yield for bromine atoms is attained. Substitution of the chlorinated solvents by other more environmentally benign organic solvents has been attempted and good results are obtained for methyl pivalate.

Aqueous N-alkylation of amines using alkyl halides: direct generation of tertiary amines under microwave irradiation
Yuhong Ju and Rajender S. Varma
Green Chemistry , 2 0 0 4 , 6 , 2 1 9 – 2 2 1

Direct formation of tertiary amines via N-alkylation of amines by alkyl halides occurs in aqueous media under microwave irradiation. This greener alternative is also a useful and powerful method to construct C–N bond without using any transition metal catalysts.



Direct mono-N-alkylation of amines in ionic liquids: chemoselectivity and reactivity
Cinzia Chiappe* and Daniela Pieraccini
Green Chemistry, 2003, 5, 193–197

A simple method for the N-alkylation of primary amines was developed using ionic liquids as solvent in order to prepare secondary amines selectively. In ionic liquids overalkylation of the initially produced secondary amines is in general markedly reduced. Various amines, alkyl halides and sulfonates were examined. The observed selectivities between mono- and dialkylation are typically on the order of 9+1, or higher. Only in the cases of allyl or benzyl bromides does the reaction give the corresponding tertiary amines exclusively. The relative nucleofugality of chloride, bromide, iodide and tosylate with several primary amines was also evaluated, as well as the effect of caesium hydroxide.

Inactivation of 5-HT2C Receptors Potentiates Consequences of Serotonin Reuptake Blockade

Abstract: The enhancement of central serotonin system function underlies the therapeutic effects of selective serotonin reuptake inhibitors (SSRIs), which have become the most commonly used class of antidepressant agents. However, many individuals experience depressive episodes that are resistant to SSRI treatment. Homeostatic mechanisms that limit the extent to which SSRIs enhance serotonergic neurotransmission have been implicated in this phenomenon. Here, we report a novel strategy for enhancing the efficacy of SSRIs. Using in vivo microdialysis methods in rats, the nonselective 5-HT2 receptor antagonist ketanserin was observed to produce a robust augmentation of citalopram-, fluoxetine-, and sertraline-induced elevations of hippocampal extracellular serotonin levels. Similar effects were also observed in cortex. The potentiation of SSRI-induced increases in hippocampal serotonin levels was reproduced by the 5-HT2C receptor-selective antagonists SB 242084 and RS 102221, but not by the 5-HT2A receptor-selective antagonist MDL 100 907. Although 5-HT2C receptor antagonists augmented the actions of SSRIs, they had no effect on extracellular serotonin levels or tail suspension responses when administered alone. These results were in strong accord with independent findings using a line of 5-HT2C receptor-null mutant mice. Although this mutation did not affect baseline extracellular serotonin levels or tail suspension test (TST) behavior, it enhanced fluoxetine effects on serotonin levels and immobility in the TST. These findings reveal an unanticipated pharmacological action of 5-HT2C receptors that warrants consideration in the development of novel strategies for the treatment of depression.

Use of GHB Compounds by HIV-Positive Individuals
Alvaro Camacho, Scott Matthews, Joel Dimsdale
American Journal on Addictions 13(2), 120 (2004)


Abstract
Gamma hydroxybutyrate (GHB) has been used by body-builders to enhance performance and by young adults in rave parties. Warnings have been posted about its addictive potential. The use of these dietary compounds is currently banned by the Food and Drug Administration, but they are widely available through the Internet and in certain communities. The purpose of the study was to examine the use of these compounds by HIV-positive individuals and to investigate their knowledge of the addictive potential of GHB and its related dietary compounds. One hundred HIV-positive individuals from the UCSD outpatient HIV clinic responded to an anonymous survey that inquired about their knowledge, use, and effects produced by GHB containing dietary compounds. The most common reported dietary compound beside GHB was Growth Hormone Release Extract (GHRE). Fifty-two percent of individuals reported using at least one GHB containing dietary compound. Gay subjects reported the highest use of GHB compounds (76.9%; p ≤ 0.001). The most common effect reported by users was increased energy (71%). Only 24% of the total responders knew about GHB's addictive potential. Among reported users of GHB containing compounds, fourteen (27%) knew about its addictive potential and nine (17%) knew that the compound is illegal. This study shows that HIV-positive gay individuals attending our clinic are using GHB compounds. Reported GHB users have limited knowledge about its addictive potential and serious adverse effects. More controlled studies are needed to evaluate long-term effects of dietary compounds containing GHB, especially among HIV-positive individuals who are actively receiving antiretroviral treatment.

Gamma-Hydroxybutyric Acid: Patterns of Use, Effects and Withdrawal
Karen Miotto, Jack Darakjian, Janice Basch, Shanna Murray, Jennifer Zogg, Richard Rawson
American Journal on Addictions 10(3), 232-241 (2001)


Abstract
Gamma-hydroxybutyric acid (GHB) is gaining popularity as a drug of abuse. Reports of toxicity and lethality associated with GHB use have increased. This survey study was designed to identify patterns of GHB use, its effects, and withdrawal syndrome. A survey inquiring about the effects of GHB was administered to 42 users. The results showed that GHB was used to increased feelings of euphoria, relaxation, and sexuality. Adverse effects occurred more frequently in daily users and polydrug users than in occasional GHB users. Loss of consciousness was reported by 66%, overdose by 28%, and amnesia by 13% of participants during GHB use and by 45% after GHB use. Three daily users developed a withdrawal syndrome that presented with anxiety, agitation, tremor, and delirium. Participants described GHB intoxication as having similarities to sedative-hypnotic or alcohol intoxication. Regular use has been shown to produce tolerance and dependence. Participants dependent on GHB reported using multiple daily doses around the clock. High frequency users appeared at the greatest risk for developing withdrawal delirium and psychosis after abrupt discontinuation of GHB use.

I can't find it on esp@cenet, there are two patents from him that have nothing to do w/ phenetylamines, he seems to have several research interests.

(Karel's voice:) This is Part 1* of Leminger's series "The Chemistry of Alkoxylated Phenethylamines".   It contains a preparation of syringaldehyde by Reimer-Tiemann formylation of 2,6-dimethoxyphenol (33% yield), etherification
of that and other phenols with alkyl iodides (67-81%) and condensation of the resulting benzaldehydes with
nitromethane in ethanolic KOH (55-67%).
