Abstract A simple, efficient, and general method has been developed for the one-pot, three-componentsynthesis of α-amino phosphonates from a condensation reaction of trialkyl phosphite, aldehydes, and amines in the presence of a catalytic amount of succinic acid (8.5 mol %) (for the first time) under solvent-free conditions. The advantages of this protocol are excellent yields, short reaction time

catalytic amount of tin(II) salts, the three-component Kabachnik-Fieldsreaction involving aldehydes, amines, and diethyl phosphite proceeded smoothly to afford the corresponding α-aminophosphonates in good to high yields. These reactions were carried out undersolvent-freeconditions. α-aminophosphonates - catalysis - imines - Lewis acids - solvent-free
