  Aldehyde as a Traceless Directing Group for Rh(III)-Catalyzed C–H Activation: A Facile Access to Diverse Indolo[1,2-a]quinolines

  摘要：

  The aldehyde group has been developed for the first time as a traceless directing group to promote regioselective Rh(III)-catalyzed C-H activation/cyclization of indolyl aldehydes with alkynes. This protocol streamlines access to a variety of appealing indolo[1,2-a]quinoline structures. As illustrative examples, a concise three-step synthesis of indolo[1,2-a]quinoline-based sensitizers is accomplished that exhibits the potential of C-H activation in the construction of organic optoelectronic materials.

• A carbon nitride supported copper nanoparticle composite: a heterogeneous catalyst for the N-arylation of hetero-aromatic compounds
  作者：Debkumar Nandi、Samarjeet Siwal、Kaushik Mallick

  DOI：10.1039/c6nj03584a

  日期：——

  nitride supported copper nanoparticle composite (Cu–gCN) has been found to be an active catalyst for the N-arylation of hetero-aromatic systems (pyrrole, pyrazole, and substituted indole) and benzamide molecules, with high product selectivity and good to excellent yields, using substituted aryl bromide as a coupling partner. The intercalated structure and the amine functional group of the carbon nitride

  已发现石墨碳氮化物负载的铜纳米颗粒复合材料（Cu–gCN）是杂芳族体系（吡咯，吡唑和取代的吲哚）和苯甲酰胺分子的N-芳基化反应的活性催化剂，具有较高的产品选择性和良好的选择性。使用取代的芳基溴化物作为偶联伙伴可达到极好的收率。氮化碳的插入结构和胺官能团阻止了反应过程中催化活性铜物质的聚集，可循环性研究表明催化剂的性能稳定，而催化活性没有明显损失。
• Weak Coordinating Carbonyl-Directed Rhodium(III)-Catalyzed C–H Activation at the C4-Position of Indole with Allyl Alcohols

  日期：2020.4.17

  coupling of allyl alcohols at the C-4 position of indole derivatives under the C–H activation conditions catalyzed by Rh(III) is reported. This results in alkylation at the C-4 position of indole derivatives exclusively. The obtained product forms a tricyclic derivative under aldol reaction conditions, which can be a potential precursor for synthesizing a few alkaloid molecules such as ergot, hapalindole

  据报道，在Rh（III）催化的CH活化条件下，吲哚衍生物的C-4位烯丙醇的弱配位羰基定向偶联。这仅导致吲哚衍生物的C-4位烷基化。所获得的产物在醛醇缩合反应条件下形成三环衍生物，其可以是合成一些生物碱分子如麦角，卤代吲哚生物碱和相关杂环化合物的潜在前体。

  Based on 5-HT1A and 5-HT7 ligand MR25003 scaffold, a new series of 1-aryl indole analogues were prepared and evaluated against 5-HT7 receptors. Modulations of aryl moieties provided a large number of new indolic derivatives. Most of compounds tested have displayed 5-HT7 affinity in the nanomolar range. Among them, 1-(naphthyl)indole derivative 3p (Ki (5-HT7) = 4.5 nM) showed also a good selectivity over 5-HT1A, 5-HT2A and 5-HT6 receptors. This compound was pharmacology characterized as an antagonist. (C) 2014 Elsevier Masson SAS. All rights reserved.

  The C2-arylation of 1-(pyridin-2-yl)indole-3-carboxalde­hyde with aryl iodides was carried out in the presence of Cu2O in basic medium. This simple and efficient method led to the preparation of 1,2-diarylindole derivatives.
