Convenient methods for the synthesis of a series of organophosphorus analogs of glycine containing aminomethyl groups as well as azaheterocyclic and amino acid moieties have been developed. Aminomethylation of phosphinic acid esters with chloro-, alkoxy- and amino-substituted methyl(dialkyl)amines affords various new functionalized aminomethylphosphonites and bis(aminomethyl)phosphinates. The resulting compounds

aminomethylation of the several esters of hypophosphorous acid using chloro-, alkoxy-, and amino-substituted methylamines of various structure is proposed as convenient method for the synthesis of newfunctionalizedaminomethylphosphonites and bis(aminomethyl)phosphinates. Also O,O-diethyl(pivaloyl)phosphonite is successfully applied in the aminomethylation as a synthetic analog of unstable diethoxyphosphine.
