The method for the synthesis of 2-substituted 2-hydroxycarbonylethyl-1-aminoalkylphosphinic acids (I) (pseudo-alpha,alpha-dipeptides) from ammonium and potassium hypophosphites (II) is described. The proposed route to the synthesis of pseudo-alpha,alpha-dipeptides consists in addition hypophosphite to acrylic compounds and formation of the first phosphorus-carbon
