simple, efficient and general method has been developed for the synthesis of 1-aminoalkyl phosphonates through a one-pot reaction of aldehydes with amines in the presence of acidic aluminaundersolvent-free conditions using microwave irradiation. It was also found that acidic aluminasupportedammonium formate undersolvent-free conditions is capable of the synthesis of 1-aminophosphonates from aldehydes

1-(N-Trifluoroacetylamino)alkanephosphonate 0,0-diethyl esters 2 C, obtained from parent 1-aminoalkanephosphonic acids 1, have been selectively deprotected on the amino function affording 0,0-diethyl 1-aminoalkanephosphonates 3. Protonation constants of all amino esters 3 synthesized have been determined by potentiometric titration.
