Abstract
The present invention relates to a multi-stage process for producing substituted, optically active alcohols, comprising an enzyme-catalyzed synthesis step, in particular a synthesis step which is catalyzed by an alcohol dehydrogenase. The inventive method is particularly suitable for producing phenylephrine, i.e. 3-[(1R)-1-hydroxy-2-methylamino-ethyl]-phenol.
