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.
本文描述了拆分混合物S-(羧甲基)-(RS)-半胱
氨酸的方法。这是通过使用1-苯基
乙胺的光学异构体实现的。这个过程可以简单地获得S-(羧甲基)-(R)-半胱
氨酸,这对于制药目的非常重要,并且是从合成半胱
氨酸中制备的。
