An efficient, easy and sustainable amidation of a set of non-activated carboxylic acids with anilines, assisted by CAL-B, as biodegradable catalyst, is reported. The enzymatic amidation reactions are performed on set of nonsteroidal anti-inflammatory drugs (NSAIDs), phenoxypropionic acid and protected-prolines by direct condensation of one equivalent of carboxylic acids and two equivalents of anilines derivatives in heptane after 72?h of reaction at 80?°C. The obtained carboxylic amides are recovered with isolated chemical yields varied between moderate and excellent. Fourteen from them are reported for the first time, and an X-ray crystal is obtained for: N-(4-iodophenyl)-2-(4-isobutylphenyl)propanamide 1d.

Simple and efficient: The combination of an enzymatic, enantioinverting reaction with simple follow-up processes allows the transformation of readily available racemic compounds into versatile chiral α-substituted amides (see picture; Ms=methanesulfonyl).
