METHOD FOR PRODUCING AN OPTICALLY ACTIVE 2-METHYL-ALKANE-1-OL FROM THE CORRESPONDING 2-METHYLALK-2-EN-1-AL, COMPRISING CARBONYL-SELECTIVE REDUCTION, ENANTIOSELECTIVE HYDRATION AND LIPASE-CATALYZED, STEREOSELECTIVE ACYLATION IN ORDER TO ENRICH THE DESIRED ENANTIOMER

摘要

The invention relates to a method for producing optically active 2-methylalkane-1-ol of general formula (III), comprising the following steps: (i) carbonyl-selective reduction of 2-methylalk-2-en-1-al of general formula (I) to 2-methylalk-2-en-1-ol of general formula (II), (ii) enantioselective hydration of 2-methylalk-2-en-1-ol to give the compound of general formula (III), (iii) increasing the optical yield of the optically active 2-methylalkane-1-ol (III) obtained in step (ii) by way of a lipase-catalyzed acylation reaction, whereby R represents C1-C10 alkyl.
