| Popis: | A simple and eco-friendly nano Fe2O3 heterogeneous catalytic system is described for the synthesis of acyl thiourea derivatives from corresponding in situ generated acyl isothiocyanates and amino acid esters in acetone obtained in good yields. The structures of synthesized acyl thioureas were confimed by 1H NMR, 13C NMR, mass, and FTIR analysis. Fe2O3 NPs has been prepared via a solution combustion route using ascorbic acid as the reducing agent and ferric nitrate as the source of iron. The prepared nano material has been characterized by XRD, SEM, UV-Visible, and FTIR analysis. More prominently, the Fe2O3 and other impurities are removed though a simple work-up and the material prepared shows to be effective in catalyzing the conversion of reactants to products in good yields. Further, some of the synthesized acyl thioureas were evaluated for in vitro antibacterial activity against Staphylococcus aureus and Escherichia coli. |
