摘要：
The palladium-catalyzed allylations of chiral hydrazones bearing phosphine groups were executed successfully under neutral reaction conditions with various allylating reagents, affording optically active alpha-allyl carbonyl compounds. The systematic and stereochemical investigation of these reactions shows that the intramolecularly-substituted phosphine groups served as chiral ligands and the anionic counterparts in the allylating reagents were markedly stereoelectronically effective on asymmetric induction.
