  A base-modulated chemoselective synthesis of 3-cyanoindoles or 4-cyanoquinolines using a palladium-catalyzed N-heterocyclization

  摘要：

  A selective methodology for the synthesis of either 3-cyanoindoles or 4-cyanoquinolines via a base-modulated palladium-catalyzed reductive N-heterocyclization from a common 1-cyano-1-(2-nitrophenyl)-1-alkene precursor is described. The required starting materials were prepared either by a Kosugi Migita Stille coupling of 2-halo-1-nitrobenzenes with a tributyl(1-alkenyl)stannane or by a vicarious nucleophilic substitution (VNS) of nitrobenzenes followed by a Knoevenagel condensation with an aldehyde.

• Radical-based regioselective cross-coupling of indoles and cycloalkanes
  作者：Jianmin Xiu、Wenbin Yi

  DOI：10.1039/c5cy01907a

  日期：——

  investigation into the regiochemistry of radical functionalization of indoles using cycloalkanes through di-tert-butyl peroxide (DTBP)-promoted C(sp3)–H activation was conducted. A wide range of indoles bearing substituents at different positions was functionalized directly with simple cycloalkanes in moderate to high regioselectivity. 2-, 4- and 7-positions were mainly functionalized.

  An efficient and economical synthetic approach toward 3-cyano-1H-indoles through the reactions of 2-(2-bromophenyl)acetonitriles with aldehydes and aqueous ammonia is presented. Mechanically, this novel protocol involves a one-pot cascade procedure consisting of an aldol-type condensation, a copper-catalyzed amination by using aqueous ammonia as a cheap and safe nitrogen source, and an intramolecular

  通过2-（2-溴苯基）乙腈与醛和氨水的反应，提出了一种高效且经济的合成3-氰基-1 H-吲哚的方法。从机械上讲，这种新颖的方案涉及一锅级联程序，该程序包括醛醇型缩合，通过使用氨水作为廉价且安全的氮源的铜催化胺化，以及分子内迈克尔加成，然后进行脱氢芳构化。有趣的是，由此获得的吲哚产物被发现是通过前所未有的高度实用的糖基化程序制备吲哚2'-脱氧核糖核苷的简便底物，其中所需的C–N键形成和甲苯甲酰基保护基的去除可在一锅中完成。

  An unprecedented palladium-catalyzed cyanation of aromatic C-H bonds by using tertiary amine derived isocyanide as a novel cyano source was developed. Cu(TFA)(2) was used as a requisite stoichiometric oxidant. Mechanistic studies suggest that a tertiary carbon cation-based intermediate Is involved following the C-N bond breakage.
