Abstract Ultrasonic irradiation has been adopted in order to achieve an efficient synthesis of some novel α-aminophosphonates by Pudovik reaction. Major benefits of this method are as follows: eco-friendly, free of catalyst, high yielding, uncomplicated work-up procedure, short reaction time, and solvent free condition. Spectral characterisation and elemental analysis of the synthesized samples was carried out. In vitro antioxidant activity of the title compounds was screened by DPPH˙, O2-˙ and NO˙ scavenging methods. Good activity was shown by most of the compounds as compared with the standards.
