title: Dynamic resolution and stereoinversion of secondary alcohols by chemo-enzymatic processes.
abstract: To overcome the maximum 50% yield limitation of classical resolution methods, deracemization processes involving a racemization step (dynamic resolution) or a prochiral intermediate (stereoinversion) have been developed. The use of transition metal complexes as racemizing agents, in combination with an enzymatic reaction, has been successfully extended to the deracemization of a number of simple or functionalized sec-alcohols. A two-enzyme process has been also investigated for their sequential or simultaneous deracemization. Other prominent results arise from an (apparently general) oxidoreduction process catalyzed by a single whole-cell microorganism.
