A variety of chiral binaphthyl-based terminal-alkene-phosphine hybrid ligands were synthesized in four steps with (S)-BINOL as a starting material and utilized for the Pd-catalyzed enantioselective allylic alkylations of indoles and pyrroles to afford the desired products in high yields with good to excellent ee’s.
