Catalytic Asymmetric Hydrophosphination of ortho-Quinone Methides
An efficient catalytic asymmetric hydrophosphination of ortho-quinone methides with H-phosphine oxides is established. A chiral bifunctional squaramide is superior to catalyze this enantioselective carbon phosphorus bond formation, delivering optically active alpha-arylmethyl phosphine oxides in high yields with high enantioselectivities (up to 94% yield, 99:1 er). Additionally, employing in situ-generated o-QMs for this hydrophosphination step economically provides the corresponding phosphine oxides with comparable yield and enantioselectivity.
