Optically‐Active compounds via biocatalytic methods

Different approaches to improve the enantioselectivity of biocatalytic systems are presented. These methodologies have been successfully applied to the preparation of optically active dihydropyridine, calcium antagonists, and cis‐3‐hydroxy‐6‐acetoxy‐cyclohex‐1‐ene, a valuable chiral building block for natural products synthesis. The phenomenon of enantioselective inhibition is described and several new heterocyclic amines have been shown to be effective enantioselective inhibitors in the Candida lipase system.
