Abstract A series of α-aminophosphonate derivatives containing aminophenol moiety have been synthesized and evaluated for their antibacterial activities against two clinical strains Gram-positive and two Gram-negative applying Agar disc diffusion method, Minimal Inhibition Concentration (MIC) and Minimal Bactericidal Concentration (MBC) methods. The chemical structures of the synthesized compounds

the synthesis of α-aminophosphonates. A three-componentreaction of an amine, an aldehyde or a ketone and a dialkyl phosphite (Kabachnik–Fieldsreaction) took place in one-pot, under solvent-free conditions to afford the corresponding α-aminophosphonates in high yields and short times. The TiO2 catalyzed α-aminophosphonate synthesis in the present study perhaps represents a true three-component reaction
