Development of a novel phosphoramidite-selenide ligand for Pd-catalyzed asymmetric allylic substitution.

A novel chiral P,Se-heterodonor ligand has been designed and prepared through an efficient and simple operation. This ligand can be successfully applied to Pd-catalyzed asymmetric allylic substitution with C- and N-nucleophiles, producing a diverse range of chiral allylic products in high yields and enantioselectivities (up to 99% yield and 95% ee).
