Popis: Asymmetric hydrogenation of the C=C bond in 5-acetylamino-5-phenylpent-4-enoic acid methyl ester or N,N-dimethylamide catalyzed by rhodium complexes with chiral bisphosphine ligands (1 mol.% of the catalyst, 20 atm. of H2, MeOH, 50 °C) gives the corresponding saturated derivatives with enantioselectivity up to 40% ??.
