A simple procedure for the synthesis of á – aminophosphonates in high yields by Kabachnik – Fields reaction in one pot three component operation involving 4-aminophenol and halo/methoxy substituted benzaldehydes and dibutyl/diphenyl phosphites without using a catalyst has been employed. The structures of novel á - aminophosphonates were established by elemental analysis, IR, 1H, 13C. 31P NMR and Mass spectral data.
