Enantioselective Hydrogenation of beta-Keto Esters Catalyzed by Chiral Binaphthylbisphosphine Ruthenium Complexes
The catalytic activity and the enantioselectivity manifested by cationic chiral binaphthylbisphosphine ruthenium complexes in asymmetric hydrogenation of beta-keto esters were studied. The effects of the nature of the solvent, the reaction temperature, the pressure, addition of acids, and the reagent ratio on the yield and the degree of enantiomeric enrichment of the reaction products were examined. For hydrogenation of ethyl 4-chloroacetoacetate to form (R)- or (S)-enantiomers of ethyl 4-chloro-3-hydroxybutyrate, conditions were found which allow one to quantitatively prepare this valuable synthon with high enantiomeric purity (97-99 percent) at a low concentration of the catalyst (the ratio substrate : Ru = 10000).
