An efficient and enantioselective phospha-Michael addition of diethyl phosphite to chalcones has been established. In the presence of a catalytic amount of chiral lanthanide silylamide generated from [(Me3Si)(2)N](3)Yb(mu-Cl)Li(THF)(3) and salen, the reaction produced the target gamma-oxophosphonates with high yields and enantioselectivity.
