Numerous substituted α‐aminophosphinates were synthesized by addition of alkyl and phenyl H‐phosphinates to aromatic imines and characterized. Modest diastereoselectivity was observed in the reaction. The size of the substituents exerts a small effect on the diastereoselectivity of P C bond formation. © 2003 Wiley Periodicals, Inc.
