A series of novel α-aminophosphonates have been prepared by one-pot three-component condensation in the presence of a zinc acetate (Zn(OAc)2•2H2O) catalyst at 50°C under solvent-free conditions with excellent yields. The major advantages of the present method are high yields, a short reaction time, and solvent-free reaction conditions. Their antimicrobial activity was evaluated, and some of them showed
candidates as original organophosphorus pesticides. The DFT calculations concerning relativestability of various conformers, besides the comparison of the measured and calculated NMR spectra of selected compounds; suggest that conformational interconversion can quite easily occur in this type of molecules, so that many structures of the same compound can coexist in solution.
