Process for the separation of the optical isomers of alpha-substituted carboxylic acids.

摘要

A process is described for the separation of the optical isomers of alpha-aryl- or alpha-aryloxy- carboxylic acids by means of the stereoselective hydrolysis of racemic alkyl esters of the above acids in the presence of bacteria or their enzymes, selected from the species Brevibacterium, Bacteridium, Micrococcus, and Bacillus.
