A method for the preparation of enantiomerically pure tertiary beta - hydroxycarboxylic acids or esters thereof

摘要

A process for the preparation of an enantiomerically pure tertiary beta - hydroxycarboxylic acid or its ester, characterized in that an enantiomer mixture of compounds with an enzyme, which for the hydrolytic cleavage of an ester bond is capable, in an aqueous medium is brought into contact, so that one enantiomer of the enantiomeric mixture is hydrolysed.
