Chiral P,N,N-Ligands for Pd-Catalyzed Asymmetric Allylic Substitutions
Chiral P,N,N-ligands are a new type of ligands developed in recent years,which have been widely used in asym-metric catalytic reactions.In this study,chiral P,N,N-ligands were applied to palladium-catalyzed asymmetric allylic substitu-tion reactions.The results showed that under mild conditions,various nucleophiles containing carbon,nitrogen and oxygen could react smoothly,achieving good yields(up to 97％yield)and enantioselectivities(up to 93％ee).
