AbstractIn this paper, the recently reported chiral stationary phase [1,2] was applied to the chiral resolution of alkyl lactates in the investigation of the effect of a new asymmetric heterogeneous catalyst system (cinchonidine-modified finely dispersed polyvinylpyrrolidone-stabilized platinum clusters) in the enantioselective hydrogenation of alpha-ketoesters. The enantiomers of methyl, ethyl, isopropyl, n-propyl and n-butyl lactates were successfully resolved while the enantiomers of isobutyl lactate could not be resolved, at all. The separation of the enantiomers of isopropyl, n-propyl and n-butyl lactates are reported for the first time. The results show that the new asymmetric heterogeneous catalyst system is effective in the enantioselective hydrogenation of alpha-ketoesters.
