Abstract

Enzymatic reduction of alpha-(alkoxycarbonylamino)acetophenones with baker's yeast afforded optically active (R)-2-(alkoxycarbonylamino)-1-arylethanols. However, the reduction of pha-(benzyloxycarbonylamino)-4-methoxyacetophenone (3c) with immobilized baker's yeast gave (S)-2(benzyloxycarbonylamino)-1-(4-methoxyphenyl) ethanol. The lipase PS-catalysed transesterification of 2-(allyloxycarbonylamino)-1-arylethanols (5) using vinyl acetate as an acyl donor resulted in the formation of (S)-2-(allyloxycarbonylamino)-1-arylethyl acetates [(S)-9] and (R)-2-(allyloxycarbonylamino)-1-arylethanols [(R)-5].
