  摘要：

  Imidazoindolones are present as the key structural motif in the family of antifungals, fumiquinazolines, and the antagonist asperlicin. The first example of a Cul-catalyzed tandem intramolecular amidation forming substituted imidazoindolones from readily accessible ortho gem-dibromovinylanilines is described.

  摘要：

  开发了一种银催化的二氧化碳固定反应到 2-炔基吲哚衍生物中，以提供三环吲哚。二氧化碳选择性地固定在吲哚的N原子上，在温和的反应条件下仅进行6-endo-dig环化。没有观察到吲哚的 C3 上的羧基化。该方法适用于多种2-炔基吲哚类化合物，并以高收率得到相应产物，且不产生副产物。

  A highly efficient method of indole synthesis using gem-dihalovinylaniline substrates and an organoboron reagent was developed via a Pd-catalyzed tandem intramolecular amination and an intermolecular Suzuki coupling. Aryl, alkenyl, and alkyl boron reagents are all successfully employed, making for a versatile modular approach. The reaction tolerates a variety of substitution patterns on the aniline

• Pd-Catalyzed Tandem C−N/C−C Coupling of <i>gem</i>-Dihalovinyl Systems:  A Modular Synthesis of 2-Substituted Indoles
  作者：Yuan-Qing Fang、Mark Lautens

  DOI：10.1021/ol051286l

  日期：2005.8.1

  2-Substituted indoles were synthesized via a Pd-catalyzed tandem C-N/Suzuki-Miyaura coupling from readily prepared ortho-gemdihalovinylanilines. Optimal conditions used a Pd(OAC)(2)/S-Phos catalyst in the presence of (K3PO4H2O)-H-. and an organoboron reagent, which included boronic acids, esters, alkyl 9-BBN derivatives, and trialkylboranes. Yields of the desired indoles were good to excellent using low catalyst loadings (typically 1 mol %).
• Palladium-Catalyzed Synthesis of 2-Cyanoindoles from 2-<i>gem</i>-Dihalovinylanilines
  作者：Nicolas Zeidan、Sabine Bognar、Sophia Lee、Mark Lautens

  DOI：10.1021/acs.orglett.7b02244

  日期：2017.10.6

  An efficient Pd(0)-catalyzed synthesis of 2-cyanoindoles from 2-gem-dihalovinylanilines is reported. Few methods have aimed to synthesize these scaffolds, which are found in many natural products and have high bioactivity. This protocol features a robust catalyst system utilizing Zn(TFA)(2) to prolong the catalytic activity. Additionally, the amount of cyanide in the reaction phase is minimized by taking advantage of the solubility of Zn(CN)(2) in a two-solvent mixture.
