ChemInform Abstract

Hydrolysis of the prochiral diesters (I) in the presence of Pseudomonas lipases K-10 and P-30 leads to the (R)-monoesters (II), whereas with the Candida cylindracea lipase OF-360 the (S)-monoesters ( II) are obtained. In contrast, the stereochemical outcome of the Pseudomonas lipase AK mediated hydrolysis is found to depend on the substituents.
