FOERFARANDE FOER FOERDELNING AV RACEMATET S-(KARBOXI-METYL)-(R,S)-CYSTEIN I ISOMERER (B)

摘要

There is described the resolution of the racemate S-(carboxymethyl)-(RS)-cysteine. It is carried out by means of the optical isomers of 1-phenyl-ethylamine. This process makes it possible to obtain in a simple manner S-(carboxymethyl)-(R)-cysteine which is important for pharmaceutical purposes and is made from synthetically produced cysteine.
