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

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
