摘要：

Polymer-supported chiral phosphinooxazolidine (POZ) ligands 9a-c and cationic palladium-POZ catalysts 16a-c have been prepared. The former ligands were used in the Pd-catalyzed asymmetric allylic alkylation, while the latter catalysts were used in the Diets-Alder reaction to afford good to excellent enantioselectivities (Pd-catalyzed allylation: up to 99% ee, Diets-Alder reaction: up to 92% ee).
