  摘要：

  本文阐述了在无溶剂条件下，利用多种醛、苯偶酰、脂肪族和芳香族一级胺以及乙酸铵作为原料，通过Fe_3O_4纳米颗粒作为催化剂，实现多组分、一锅法、高效且环境适应性的新型多取代咪唑合成方法。研究表明，Fe_3O_4纳米颗粒在这一合成过程中表现出高效的催化作用。利用这一优势，可以高产率和高纯度地制备出若干具有重要药学意义的多取代咪唑分子。该方法操作简便、反应迅速，适用于咪唑衍生物的合成。所有产物均通过其红外光谱和核磁共振光谱数据得以推导。Fe_3O_4纳米颗粒则通过粉末X射线衍射（XRD）、透射电子显微镜（TEM）以及傅里叶变换红外光谱（FT-IR）进行表征。

  Multicomponent, one-pot, highly efficient, and environmentally adapted synthesis of some novel polysubstituted imidazoles by the use of various aldehydes, benzil, aliphatic, and aromatic primary amines and ammonium acetate in the presence of Fe_3O_4 nanoparticles as catalyst under solvent-free condition is explained. A highly efficient role of Fe_3O_4 nanoparticles as catalyst in this synthesis was shown. By this advantage, several polysubstituted imidazoles as pharmaceutical important molecules can be prepared in high yield and high purity. This method is very easy and rapid for the synthesis of imidazole derivatives. All products were deduced from their IR and NMR spectroscopic data. The Fe_3O_4 nanoparticles were characterized by powdered X-ray diffraction (XRD), transmission electron microscopy (TEM), and FT-IR spectroscopy.
