  • Multisite Solid Catalyst for Cascade Reactions: The Direct Synthesis of Benzodiazepines from Nitro Compounds
    作者:Maria J. Climent、Avelino Corma、Sara Iborra、Laura L. Santos
    DOI:10.1002/chem.200900492
    日期:2009.9.7
    Substituted 1,5‐benzodiazepines are selectively synthesized in one pot from substituted nitroaromatics and ketones. The reaction is performed in the presence of hydrogen and in the absence of solvent by using a bifunctional solid catalyst with a chemoselective hydrogenation functional group capable of reducing the nitro group to a diamino group and an acid functional group, which catalyzes the cyclocondensation

    Various biologically important 1,5-benzodiazepine derivatives were efficiently synthesized in excellent yields using catalytic amounts of NBS (10 mol %). This inexpensive, nontoxic, and readily available catalyst efficiently catalyzes the condensation of several aromatic as well as aliphatic ketones with substituted o-phenylenediamines.

    An environmentally benign and clean biopolymer-based heterogeneous nanocatalyst was prepared and its properties and morphology were characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD). Then, its catalytic activity was investigated in two important organic reactions. In these reactions, efficient and selective syntheses of 1,2-disubstituted benzimidazole and 1,5-benzodiazepine derivatives were carried out using 1,2-diamines and aldehydes or ketones in the presence of a catalytic amount of magnetically recoverable chitosan-supported iron oxide nanoparticles (Fe3O4/chitosan), as a biodegradable nanocomposite, in ethanol at ambient temperature in high yields. The Fe3O4/chitosan nanocatalyst can be recovered easily and reused without any significant loss of the catalytic activity.

    However, direct reactions of o-phenylenediamine with oximes (acetone oxime, acetophenone oxime, and benzophenone oxime) as ketone equivalents did not occur. In the course of present investigations, it is found that dichloroamine-T can be an efficient reagent for the conversion of oximes into the corresponding carbonyl compounds. As a part of a research program related to the synthetic study of pharmacologically
    报告指出,用丙酮二甲酸、丙酮和苯乙酮处理邻苯二胺,得到2,4,4-三甲基-3H-5-氢-1,5-苯二氮卓。然而,邻苯二胺与作为酮等价物的肟(丙酮肟、苯乙酮肟和二苯甲酮肟)没有发生直接反应。在目前的研究过程中,发现二氯胺-T可以是将肟转化为相应的羰基化合物的有效试剂。作为与药理学上感兴趣的苯二氮卓化合物的合成研究相关的研究计划的一部分,本文从使用二氯胺-T获得的杂芳酮和丙酮等价物合成1H-1,5-苯二氮卓衍生物。另一方面,当二胺(1,2-苯二胺或1,2-萘二胺)与杂环酮(乙酰基吡啶或乙酰基吡嗪)存在浓的情况下。HCl和SiO2回流,以高收率分离出黄色结晶固体的喹喔啉衍生物
  • 1,5-Benzodiazepine synthesis via cyclocondensation of 1,2-diamines with ketones using iron-based metal–organic framework MOF-235 as an efficient heterogeneous catalyst

    heterogeneous catalyst for the synthesis of 1,5-benzodiazepines by the cyclocondensation of 1,2-diamines with ketones. Excellent conversions to 1,5-benzodiazepines were achieved in the presence of 5 mol% MOF-235 catalyst using molecular oxygen in air as the stoichiometric oxidant. The Fe-MOF exhibited higher catalytic activity for the cyclocondensation reaction than those of other MOFs including MOF-5, Mn(BDC)
    合成了基于铁的晶体金属-有机骨架MOF-235,并通过X射线粉末衍射(XRD),扫描电子显微镜(SEM),透射电子显微镜(TEM),热重分析(TGA),傅里叶变换红外进行了表征(FT-IR),原子吸收分光光度法(AAS)和氮物理吸收测量。MOF-235可用作多相催化剂,用于通过1,2-二胺与酮的环缩合反应合成1,5-苯并二氮杂s。使用空气中的分子氧作为化学计量的氧化剂,在5 mol%MOF-235催化剂存在下,可以实现极佳的1,5-苯并二氮杂s转化。Fe-MOF对环缩合反应的催化活性高于MOF-5,Mn(BDC),MOF-199和Ni 2等其他MOF。(BDC)2(DABCO)。可以通过离心从反应混合物中分离出Fe-MOF催化剂,并且可以将其回收并重复使用数次而不会显着降低催化活性。据我们所知,以前没有使用MOF作为多相催化剂合成1,5-苯并二氮杂pine。
