alpha-Acylenamines with terminal double bond CH2=CH(NR2)COMe add dialkyl hydrogen phosphites to form only the Michaelis adducts. Contrary to that hydrophosphorylation of a-formylated enamines proceeds regiospecifically at C=O bond. Subsequent isomerization of the products of 1,2-addition and the cleavage of P-C bond of the intermediate alpha-keto-beta-aminophosphonate yields N, N-disubstituted alpha-aminocarboxylates.
