study was designed to determine whether whole cells or crude enzyme
extracts are more effective for preparative-scale ketone reductions
by dehydrogenases as well as learning which cofactor regeneration
scheme is most effective. Based on results from three representative
ketone substrates (an α-fluoro-β-keto ester, a bis-trifluoromethylated acetophenone, and a symmetrical
β-diketone), our results demonstrate that several nicotinamide
cofactor regeneration strategies can be applied to preparative-scale
dehydrogenase-catalyzed reactions successfully.
