  摘要：

  功能化三酸酰亚胺的壳聚糖被应用于通过一次性反应合成苯二氮杂烯类化合物，该反应涉及1,2-苯二胺与二甲酮、芳香醛或异氰酸酯及梅尔德鲁姆酸的反应。通过FT-IR（红外光谱）、XRD（X射线衍射）、DSC（差示扫描量热法）和TGA（热重分析）确认了功能化三酸酰亚胺的壳聚糖。为了研究该反应的范围和局限性，使用了不同的芳香醛和异氰酸酯作为底物。该方法的几个重要特点包括短反应时间内得到良好的产率、实验简便、产品范围广泛、催化剂可回收及低催化剂用量。

  Highly effective one-pot synthesis of benzo[b][1,5]diazepines has been achieved by three-component (or, in situ, including catalyst and solvent, five-component) reaction of aromatic diamines, Meldrum’s acid, and isocyanides catalyzed by magnetite (Fe3O4) nanoparticles. Pharmaceutically and biologically active heterocyclic compounds including benzodiazepine derivatives were efficiently synthesized in excellent yields and short reaction times at room temperature. The significant features of the Fe3O4 nanoparticles are: easy preparation, cost-effectiveness, high stability, easy separation, low loading, and reusability of the catalyst. The heterogeneous nanoparticles were fully characterized by XRD, EDX, BET, SEM, TEM, and FT-IR analysis.

  CoFe₂O₄@SiO₂-PrNH₂ nanoparticles have been used as an efficient catalyst for the preparation of benzodiazepines by multi-component reactions of 1,2-phenylenediamine, dimedone, different aldehydes or Meldrum’s acid and isocyanides. This method provides several advantages including mild reaction conditions, the applicability to a wide range of substrates, the reusability of the catalyst and low catalyst loading.

  A novel and efficient method has been developed for the synthesis of tetrahydro-2,4-dioxo-1H-benzo[b][1,5]diazepine-3-yl-2-methylpropanamide derivatives using an aromatic diamine, Meldrum's acid, and an isocyanide in CH2Cl2 at ambient temperature in high yields without using any catalyst or activation. The procedure provides an alternative method for the synthesis of benzo[b][1,5]diazepine derivatives. These compounds have closely related ring systems such as triflubazam, clobazam, and 1,5-benzodiazepines, which have a broad spectrum of biological activities.
