摘要：

H-8-BINOL-derived phosphine-oxazolines complexed with iridium were successfully applied for the asymmetric hydrogenation of the carbon-carbon double bond of exocyclic alpha,beta-unsaturated carbonyl compounds. A valuable series of alpha-chiral cyclic ketones, lactones, and lactams were therefore provided via the reaction in high yields and good to excellent enantioselectivity of up to 95% ee. The effects of the ligands and substrate structures on the asymmetric catalysis were also discussed.
