Abstract An efficient method has been developed for the preparation of α-aminophosphonates by using zinc di(l-prolinate) as a catalyst under mild reaction conditions. The method has the advantages of high yields, short reaction times, and easy workup conditions. An efficient method has been developed for the preparation of α-aminophosphonates by using zinc di(l-prolinate) as a catalyst under mild reaction

Herein we introduce a new catalyst for the Kabachnik–Fields reaction, [Ce(L-Pro)]2(Oxa), using a very accessible, simple and efficient methodology for α-aminophosphonate synthesis using an aromatic aldehyde, an aromaticamine and diphenyl phosphite. This procedure was developed using a low catalyst loading of cerium(III) prolinate and it has allowed for the recycling of the catalyst.
