摘要

A process for obtaining the optical isomers of the racemic threo-beta- (p-nitrophenyl) -serine methyl ester, characterized by fractionally crystallizing the tartaric salt of the threo-beta- (p-nitrophenyl) methyl ester racemic serum, obtaining in the manner known per se from the produced diastereomeric salts, the free methyl esters of the optically active threo-beta- (p-nitrophenyl) -serines.
