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

An atom-efficient, one-pot, three-component synthetic methodology has been developed for the preparation of α-aminophosphonates using the crystalline CuO- nanopowder as catalyst in solvent-free and ambient conditions, for the first time. The reaction involves the use of carbonyl compounds, amines and trimethyl phosphite. A wide range of substrates is compatible in this reaction, producing excellent
