Abstract

RE-CWVP (rotary evaporator equipped with a circulating water vacuum pump)–assisted synthesis is reported as an extremely efficient, facile, and clean procedure for the preparation of α-aminophosphonates in organic synthesis and industrial processes. The title α-aminophosphonates are obtained in good to satisfactory yields by the method and characterized by means of IR, 1H NMR, 31P NMR, 13C NMR, and mass spectrometry.
