N-Acetyl-L-cysteine was reacted with 2-(2-, 3-, or 4-methylphenyl)-oxiranes to give mixtures of the two possible regio isomers N-acetyl-S-[1-(2-, 3-, or 4-methylphenyl)-2-hydroxyethyl]-L-cysteine and N-acetyl-S-[2-(2-, 3-, or 4-methylphenyl)-2-hydroxyethyl]-L-cysteine, respectively. These were isolated in pure form by h.p.l.c.. The diastereomers were characterized by
