  Efficient Reagents for the Synthesis of 5-, 7-, and 5,7-Substituted Indoles Starting from Aromatic Amines:  Scope and Limitations

  摘要：

  Upon reaction with IPy(2)BF(4), 4-substituted anilines give regioselectively the corresponding o-iodoanilines in nearly quantitative yield, in a process that can be carried out on a multigram scale. Palladium-catalyzed coupling of the resulting 2-iodoanilines with (trimethylsilyl)acetylene (TMSA), followed by efficient CuI-mediated nitrogen cyclization onto alkynes with concurrent elimination of the TMS substituent, allows a straightforward elaboration of 5-mono- and 5,7-disubstituted indoles from aromatic amines. This new approach to the aforementioned indoles does not requires protective groups on nitrogen at any step and can be adapted for preparing related 7-manosubstituted indoles. Moreover, examples iterating the process are given, allowing bis-annulation and sequential double annulation and resulting in synthesis of benzodipyrroles. Additionally, suitable conditions for iodination of some of the target indoles with IPy(2)BF(4) are discussed.

• Synthesis of diverse indole libraries on polystyrene resin – Scope and limitations of an organometallic reaction on solid supports
  作者：Kerstin Knepper、Sylvia Vanderheiden、Stefan Bräse

  DOI：10.3762/bjoc.8.132

  日期：——

  The synthesis of diverse substituted indole structures on solid supports is described. The immobilization of nitrobenzoic acid onto Merrifield resin and the subsequent treatment with alkenyl Grignard reagents delivered indole carboxylates bound to solid supports. In contrast to results in the liquid phase, ortho,ortho-unsubstituted nitroarenes also delivered indole moieties in good yields. Subsequent

  描述了在固体支持物上合成多种取代的吲哚结构。将硝基苯甲酸固定在 Merrifield 树脂上并随后用链烯基格氏试剂处理将吲哚羧酸盐结合到固体载体上。与液相中的结果相反，邻位、邻位未取代的硝基芳烃也以良好的产率递送吲哚部分。随后的钯催化反应（Suzuki、Heck、Sonogashira、Stille）在裂解后通过四个步骤以中等至良好的产率传递所需的分子。介绍了范围和限制。

  日期：2003.8.1

  [reaction: see text] Bartoli indole synthesis has been performed for the first time on solid supports. Starting from Merrifield resin, immobilization of five nitro benzoic acids was performed. Addition of four different alkenyl Grignard reagents and basic cleavage leads to substituted methyl indole carboxylates in excellent purities. Features of this reaction are the stability of halide groups, ester
