User Picture       A possible new pathway for ICE

I've found some refs for ICE and a route like this:

On Beilstein (BRN 149933) there are 5 type of reactions; I've found that on Yakugaku Zasshi (a Japanese journal of pharmacological chemistry), (1948), 68, 70 it is possible make ICE from 1,2-dibromo-1-phenylpropane (from propenylbenzene!) and urea.

Other refs are:

on the same journal, (1978), 98(5), 611-617;
Heterocycles, (1997), 6(9-10), 1604-9
Berichte, (1931), 64, 1076-86 (in german!)
J. Med. Chem., (1963), 6, 266-72 (with CNBr, usual route)

On Chemical Abstract:

93:220636x --> Eur. J. Med. Chem. - Chem. Ther., (1980), 15(2), 111-17 (also this in german)

Unfortunately I cant achieve these refs and I dont know gernan, so I someone could please help me... wink

User Picture       1-Phenyl-1,2-Dibromopropane + Urea -> 4-MAR
(Rated as: good read)

Here's the CA entry from the abovementioned article which supposedly would tell us how to go from 1-phenyl-1,2-dibromopropane to 4-MAR with urea, but unfortunately it seems like this short abstract is incomplete. But nevertheless, it still contained some interesting information about ephedrine-relaed chemistry.
