Asymmetric Diels-Alder reaction between 3,4-dimethyl-1-phenylphosphole and (Z/E)-diphenyl-1-styrylphosphine

Asymmetric cycloaddition reaction between 3,4-dimethyl-1-phenylphosphole and (Z/E)-diphenyl-1-styrylphosphine was promoted by the palladium complex containing ortho-metalated (S)-[1-(dimethylamino)ethyl]naphthalene as the chiral auxiliary.
