Process for preparing optically active 4-halogeno-1, 3-butanediol and its derivatives by microorganism

摘要

A process for preparing an optically active 4-halogeno-1,3-butanediol and (R)-1,2,4-butanetriol or (S)-3-hydroxy-γ-butyrolactone which comprises reacting a racemic 4-halogeno-1,3-butanediol with a specific microorganism belonging to the genus Pseudomonas.
