A Straightforward Deracemization of sec -Alcohols Combining Organocatalytic Oxidation and Biocatalytic Reduction

An efficient organocatalytic oxidation of racemic secondary alcohols, mediated by sodium hypochlorite (NaOCl) and 2‐azaadamantane N ‐oxyl (AZADO), has been conveniently coupled with a highly stereoselective bioreduction of the intermediate ketone, catalyzed by ketoreductases, in aqueous medium. The potential of this one‐pot two‐step deracemization process has been proven by a large set of structurally different secondary alcohols. Reactions were...
