英文摘要: A series of new chiral phosphine-aminophosphine ligands have been prepared via a two- or three-step transformation from commercially available and inexpensive (S)-1-phenylethylamine, and successfully used in the rhodium-catalyzed asymmetric hydrogenation of various enamides, beta-dehydroamino acid esters, and dimethyl itaconate. The results show that the ligand structure plays an important influence on both the reactivity and enantioselectivity. Ligand 2d bearing a N-H proton and two F-atoms on the 3,5-positions of the phenyl ring of the aminophosphino moiety was most effective for the hydrogenation of enamides and (Z)-beta-aryl-beta-(acylamino)acrylates, whereas ligand lb showed the highest enantioselectivities in the hydrogenation of (Z)-beta-alkyl-beta-(acylamino)acrylates and dimethyl itaconate.
