摘要 |
A process for producing an optically active alpha -substituted organic acid represented by formula (II), comprising the steps of (a) treating a racemic alpha -substituted nitrile or amide represented by formula (I) with a microorganism selected from the group consisting of the microorganisms of genuses Alcaligenes, Pseudomonas, Rhodopseudomonas, Corynebacterium, Acinetobacter, Bacillus, Mycobacterium, Rhodococcus and Candida, or preparations thereof; and (b) recovering the resulting optically active alpha -substituted organic acid represented by formula (II): <CHEM> wherein R1 and R2 each represent a halogen atom, a hydroxyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aryloxy group or a substituted or unsubstituted heterocyclic group with the proviso that R1 and R2 are different from each other; and X represents a nitrile group or an amido group, <CHEM> wherein R1 and R2 are as defined above. > |
