Abstract

The present invention concerns a process for the stereoselective enzymatic reduction of keto group-containing compounds such as N-(4-(2-chloroacetyl)phenyl)methanesulfonamido to form the corresponding hydroxyl-group containing compound. The process is selective for the D(+) enantiomer and is catalyzed by enzymes such as oxido-reductase or dehydrogense, or by microorganisms such as Hansenula, Rhodococcus, or Norcardia species.
