An efficient and high-yield synthesis of a class of new α-aminophosphonate derivatives as diethyl α-aryl/2-thienyl-α- [2-(phenylthio)phenylamino]methylphosphonates 6a-j in short reaction times from three component coupling reactions (Kabachnik-Fields reaction) of 2-aminodiphenylsulfide 3, substituted phenyl/heterocyclic aldehydes 4a-j, and diethyl phosphite 5 is reported. The reaction proceeds smoothly in the presence of the catalyst, nano-silica-supported boron trifluoride (BF3· SiO2) without using solvent under microwave irradiation. The title compounds were tested for in vitro antibacterial and antifungal activities at concentrations of 100 and 200 μg/disc. Minimum inhibitory concentrations (MICs) were also examined.
