N-protected α-aminoalkylphosphinic acids by the reaction of N,N′-benzylidene- or N,N′-alkylidenebiscarbamates, trifluoroaceticanhydride and the corresponding alkylphosphonous acids in methylene chloride or toluene is described. The results obtained confirm the earlier proposed mechanism for amidoalkylation of hydrophosphorylic compounds involving an Arbuzov-type reaction step.
