  A Stereoselective Inverting sec-Alkylsulfatase for the Deracemization of sec-Alcohols

  摘要：

  A metallo-beta-lactamase-type alkylsulfatase was found to catalyze the enantioselective hydrolysis of sec,alkylsulfates with strict inversion of configuration. This catalytic event, which does not have an analog in chemocatalysis, yields homochiral (S)-configurated alcohols and nonreacted sulfate esters. The latter could be converted into (S)-sec-alcohols as the sole product in up to > 99% ee via a chemoenzymatic deracemization protocol on a preparative scale.
