A simple, efficient, and general method has been developed for the one-pot synthesis of α-aminophosphonic esters, under solvent-free conditions, with the use of CaCl 2 as a Lewis base catalyst. The esters were obtained under mild conditions and in high yield (80 to 96%) and purity. They were synthesized by the reaction of diethyl phosphite with a mixture of aldehydes and amines, in the presence of

Abstract A catalyst-free practical version of Kabachnik-Fields strategy has been developed for the efficient and straightforward one-potsynthesis of diversely substituted α-aminoallylphosphonates, a limitedly reported class of biologically important α-aminophosphonates family. The protocol offers many advantages including avoidance of additive/catalyst, one-pot multicomponent approach, operational
