Abstract

Palladium complexes with an axially chiral N–Ar framework have been developed. These complexes showed high stereoselectivities in asymmetric allylic arylation to achieve the kinetic resolution of Morita–Baylis–Hillman adducts, affording up to 99% ee of (E)-allylation products and 92% ee of recovered Morita–Baylis–Hillman adducts.
