In this Letter, we report a preparation of optically active α-substituted carboxylic acids via a novel enzymatic deracemization reaction using whole cells. This deracemization reaction inverts the chirality of one enantiomer of a racemate to the other antipode, resulting in an optically active compound starting from a racemic mixture. Thus this process is entirely different from the above-mentioned dynamic resolution, 2 because in this reaction the starting material and ...
