The present invention relates to a process comprising hydrolysis or trans esterification of one of the two enantiomeric forms of a racemic or enantiomerically enriched ester of formula (I) or (IV) by a higher rate than the other by an enzyme to give an ester and an acid (III) or two different esters (V) and (VI) with different R groups both with increased enantiomeric purity and an esterification process of a racemic or enantiomerically enriched acid (VII) by an enzyme to give an ester and an acid both with increased enantiomeric purity.
