α-Aminophosphonates play an important role across several fields, including organic synthesis and various potential applications. This review paper surveys recent achievements in the synthesis of α-Aminophosphonates, it summarizes the main synthetic routes towards α-Aminophosphonates that are known and it describes their biological proprieties from January2010 till December 2020: Special attention is devoted to green chemical approaches including catalysts, ultrasonic and microwave irradiations. We hope this paper will be a useful resource for researchers and that it will help them to work in this emerging research area.
In this present study, we describe a simple, effective and greener one‐pot microwave‐assisted synthesis of novel α‐sulfamidophosphonates 4(a–l), and 5(a, b) that were rationally designed and synthesized following the principle of the superposition of bioactives substructures. This reaction was accomplished by the condensation of various aromatic aldehydes, sulfamide and diethyl phosphite via the Kabachnik‐Fields reaction using ethanol as solvent under catalyst‐free conditions. The corresponding products were obtained with good yields, in short reactions time and no side product was observed. All the newly synthesized compounds were systematically characterized by IR, 1H NMR, 13C NMR and 31P NMR analysis and the structures of the compounds 4 b and 4 c were further analyzed by single crystal X‐ray diffraction.
