METHOD FOR THE PRODUCTION OF OPTICALLY ACTIVE 2-AMINO-,2-CHLORO-,2-HYDROXY OR 2-ALKOXY-1-ALCOHOLS

摘要

The invention relates to a method for the production of optically active 2- amino-, 2 chloro-, 2-hydroxy- or 2-alkoxy-1-alkanoles by catalytic hydrogenation of corresponding optically active 2-amino-, -chloro-, 2-hydrox y- and 2-alkoxy carboxylic acids or the acid derivatives thereof. According to the inventive method, hydrogenation is carried out in the presence of palladium and rhenium or catalysts containing palladium and rhenium.
