the synthesis of α-aminophosphonates. A three-componentreaction of an amine, an aldehyde or a ketone and a dialkyl phosphite (Kabachnik–Fieldsreaction) took place in one-pot, under solvent-free conditions to afford the corresponding α-aminophosphonates in high yields and short times. The TiO2 catalyzed α-aminophosphonate synthesis in the present study perhaps represents a true three-component reaction

Abstract An highly efficient and environmentally friendly process for the synthesis of α-aminophosphonates has been devised, through a one-pot three-component condensation of various aldehydes, amines and triethyl phosphate in water-ethyl lactate under ultrasonic irradiation conditions at room temperature. The expected products were obtained in high yield without the need for any additional catalyst
