## Abstract The first straightforward lipase‐catalyzed enantioselective access to enantiomerically enriched tiaprofenic acid as a versatile method in chiral separation of racemates is demonstrated. The latter was directly monitored by enantioselective HPLC using a 3,5‐dimethylphenylcarbamate deriva

Substituent effects on the enantioselectivity for the lipase-catalyzed esterifications in organic solvents were studied by use of 2-(4-substituted phenoxy)propionic acids as the substrates with various substituents of H, F, Cl, CF 3 , CH 3 , CH 3 CH 2 , and CH 3 O. The distinction in the behavior of
