AbstractA simple, efficient and general method has been developed for the high diastereoselective synthesis of α-aminophosphonates through “one-pot” three-component reaction of alkyl and aryl aldehydes with (S)-α-methylbenzylamine or (S)-3,3-dimethyl-2-butylamine and dimethyl phosphite (Kabachnik-Fields reaction), which proceeds in short time using microwave irradiation under solvent and catalyst free-conditions. This method could be useful in the large-scale synthesis of α-aminophosphonates in short reaction time
