Benzodiazepines and their derivatives are a very important class of nitrogen-containing heterocyclic compounds with biological activity that are widely used in medicine. In this study, we demonstrated synthesis of 1,5-benzodiazepines from 1,2-phenylenediamine and ketones (acetone, cyclohexanone, acetophenone, methyl ethyl ketone) in the presence of isostructural porous metal-benzenetricarboxylates
苯二氮卓类及其衍生物是一类非常重要的具有生物学活性的含氮杂环化合物,已广泛用于医学中。在这项研究中,我们证明了在存在MIL-100(M)族的等结构多孔金属-苯三羧酸盐的情况下,由1,2-苯二胺和酮(丙酮,环己酮,苯乙酮,甲乙酮)合成1,5-苯并二氮杂卓(M:V 3+,Al 3+,Fe 3+和Cr 3+)和三个多孔铝均聚物Al-BTC(MIL-96(Al),MIL-100(Al)和MIL-110(Al))。催化,理论和物理化学方法的结合表明,1,5-苯并二氮杂pine的反应速率和产率受金属离子类型和活性位点可及性的调节。在存在MIL-100(M)的情况下1,5-苯并二氮杂卓的产率与HY,H-ZSM-5,β-沸石和堇青石等沸石相当。
