Catalytic Enantioselective Synthesis of Aryl-Methyl Organophosphorus Compounds.

A catalytic enantioselective protocol for the synthesis of aryl-methyl organophosphorus compounds is reported. Utilizing a chiral phosphoric acid as a catalyst, a wide range of indole derivatives reacted with phosphorylated quinomethanes in high yield with excellent enantioselectivity. This is the first report on the application of phosphorylated quinomethanes in asymmetric synthesis.
