The reactions of dibenzylphosphine oxide with alpha,beta-unsaturated nitriles in the presence of two equivalents of NaH in (BuOMe)-O-t afforded substituted aminophospholene oxides in 20-83% yields. In the presence of bulky substituents at the alpha and gamma positions of unsaturated nitriles, cyclization of the initially formed adducts proceeds with high stereoselectivity to give the single stereoisomer of aminophospholene oxide.
