efficient one-pot, three-component, green approaches for important organic synthons. We describe here a simple, elegant and high yielding protocol for the synthesis of α-aminophosphonates in totally solvent-free, catalyst-free conditions by reacting aldehydes, amines and trimethyl phosphite at ambient temperature.

A simple and efficient method is described using glycerol as a solvent in the catalyst-free synthesis of alpha-aminophosphonates in high purity. Products are prepared by the Kabachnik-Fields reaction from amines, phosphites, and carbonyl compounds. The method does not require a toxic catalyst. (C) 2014 Elsevier Ltd. All rights reserved.
A new procedure for synthesis of $$\upalpha $$ α -aminophosphonates by aqueous formic acid as an effective and environment-friendly organocatalyst
AbstractAqueous formic acid (37%) as a green organocatalyst was used to synthesis of \(\upalpha \)-aminophosphonates in one-pot, three-componentKabachnik–Fieldsreaction. The structures of compounds were determined by FT-IR, \(}^1}\hbox H}\)-NMR and \(}^13}\hbox C}\)-NMR spectroscopy. After optimization of the experimental conditions, the reaction was carried out at \(65\,^\circ }}\hbox C}\)
