Secondaryalcoholdehydrogenase (SADH) fromThermoanaerobacterethanolicus, an NADP-dependent, thermostable oxidoreductase, reduces ethynyl ketones and ethynylketoesters enantioselectively to the corresponding propargyl (propargyl = prop-2-ynyl) alcohols. Ethynyl ketones, in general, are reduced with moderate enantioselectivity (with the exception of 4-methylpent-1-yn-3-one, which gives the (S)-alcohol
