Abstract

Enantioselective hydrogenation of seven different esters of phenylglyoxylic acid was investigated by variation of the bulkiness at ester side of the substrates [PhC (O) C (O) OR, R= Me (l), cyclohexyl (2), adamantyl (3), cis-decahydro-1-naphthyl (4), phenyl (5), 1-naphthyl (6), 2-naphthyl (7)] on Pt-alumina-cinchonidine (CD) and Pt-alumina-β-isocinchonine (β- ICN) chiral catalysts using mild experimental conditions (273 K and room temperature, ...
