Popis:	Some optically active γ-butyrolactones derivatives, useful building blocks for the synthesis of several natural products, have been obtained by a convenient procedure using catalytic asymmetric hydrogenation. 3,4-Disubstituted γ-butyrolactones were obtained in good yields and in high enantiomeric excess through the enantioselective hydrogenation of the corresponding butenolides catalyzed by BINAP-Rh or Ru complexes.
