Abstract In this research, a novel protocol for the synthesis of imidazole derivatives with various substitutions has been investigated in presence new and highly effective magnetic decorated DL-methionine amino acid grafted onto chitosan backbone by using EDTA linker (CS − MET@Fe3O4) under green chemistry conditions. The CS MET@Fe3O4 nanocomposite was properly characterized FTIR, EDX, XRD, FESEM, TGA VSM spectroscopic, microscopic, or analytical methods. used as efficient heterogeneous organocatalyst wide range three- four-substituted derivatives, an important pharmaceutical scaffold, through multicomponent reactioins (MCRs) strategy. multifunctional nanocatalyst exhibited high catalytic activity, selectivity, stability to promote reactions benzoin benzyl, different aldehyde ammonim acetate well aromatic aliphatic amine EtOH solvent. Key advantages present are excellent yields, use low loading renewable, bio-based biodegredable chitosan- acid-based nanomaterial, simple procedure preparation nanomaterial imoidazole derivatives. addition, catalyst's properties, including its properties appropriate surface area characteristicscontribute performance. Fuerthermore, can be up six cycles only slight decrease activity.
