  One-pot reduction-triggered heterocyclizations from 2-nitroanilines or 1,2-dinitroarenes to benzimidazoles were investigated in this study. In the presence of indium/AcOH in ethyl acetate at reflux, reaction of 2-nitroanilines or 1,2-dinitroarenes with R–C(OMe)3 (R=Me, Ph) produced excellent yields of the corresponding benzimidazoles within 30 min to 6 h depending on the substituents of the starting

  在此研究中，研究了从2-硝基苯胺或1,2-二硝基芳烃到苯并咪唑的一锅还原触发的杂环化反应。在乙酸乙酯中存在铟/ AcOH的条件下，回流时，2-硝基苯胺或1,2-二硝基芳烃与RC（OMe）3（R = Me，Ph）的反应在30分钟内可得到优异的相应苯并咪唑收率。 6小时取决于起始材料的取代基。在类似的反应条件下，与1,2-二硝基芳烃向苯并咪唑的铟介导的2-硝基苯胺到苯并咪唑的杂环化反应更快，并且产率更高。
• Direct Access to Dihydrobenzoimidazo[2,1‐ <i>a</i> ]isoquinolines through Ruthenium‐catalyzed Formal [4+2] Annulation
  作者：Sandip Dhole、Chung‐Ming Sun

  DOI：10.1002/adsc.201801241

  日期：2019.2

  A facile and straightforward synthesis of benzoimidazo[2,1‐a]isoquinolines through Ru(II)‐catalyzed [4+2] annulation reaction of 2‐aryl benzimidazole and styrene has been explored. Tentative mechanistic studies imply the current reaction involves sequential C−C/C−N bond formation through the ortho C−H activation of 2‐aryl benzimidazole followed by C−N reductive elimination. This newly developed strategy

  通过Ru（II）催化2-芳基苯并咪唑与苯乙烯的[4 + 2]环合反应，可以轻松，直接地合成苯并咪唑并[2,1- a ]异喹啉。初步的机理研究表明，当前的反应涉及通过2-芳基苯并咪唑的邻位CH活化依次形成CC -C / C-N键，然后再进行CN还原消除。这种新开发的策略可广泛应用，并能耐受各种2-芳基苯并咪唑和乙烯基衍生物，并为以高收率直接构建各种C6取代的苯并咪唑并异喹啉骨架提供了诱人的载体。

  compound bound to the CREB binding protein (CBP) and the first bromodomain of BRD4 (BRD4(1)) were used to guide the design of more selective compounds. The crystal structures obtained revealed two distinct binding modes. By varying the aryl substitution pattern and developing conformationally constrained analogues, selectivity for CBP over BRD4(1) was increased. The optimized compound is highly potent (Kd

  phenylenediamines and aldehydes catalyzed by a highly recyclable nonnoble cobalt nanocomposite was developed. A broad set of benzimidazoles can be efficiently synthesized in high yields and with good functional-group tolerance under additive- and oxidant-free mild conditions. The catalyst can be easily recycled for successive uses, and the process permits gram-scale syntheses of benzimidazoles.
