CuI-catalyzed N,O-arylation of (S)-prolinols and 1-bromo-2-iodobenzene afforded cyclic N,O-(1,2-phenylene)prolinols, and subsequent ortho-lithiation and phosphination provided a new type of chiral P,O-ligands. Their palladium-complex-catalyzed asymmetric
Preparation of N-phenyl-(S)-prolinol-derived P,N-ligands and their application in Pd-catalyzed asymmetric allylic alkylation

Several NPN-type ligands bearing two chiral pyrrolidinyl groups derived from N-phenyl-(S)-prolinol were prepared by two synthetic methods. Their palladium-complex-catalyzed asymmetric allylic alkylation of malonates with 1,3-diphenyl 2-propenyl acetate delivered the products with good to high enantioselectivities (84-97% ee), including an optically active fluorine-containing compound.
