  CuI-Catalyzed Tandem Intramolecular Amidation Using gem-Dibromovinyl Systems

  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.

• 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 %).
• The Role of Reversible Oxidative Addition in Selective Palladium(0)-Catalyzed Intramolecular Cross-Couplings of Polyhalogenated Substrates: Synthesis of Brominated Indoles
  作者：Stephen G. Newman、Mark Lautens

  DOI：10.1021/ja1052335

  日期：2010.8.25

  A Pd(0)-catalyzed C-N bond-forming reaction leading to the synthesis of brominated indoles is described. The use of the phosphine ligand PtBu3 is necessary for reactivity. It is proposed that the bulky ligand serves to prevent inhibition of the catalyst by facilitating reversible oxidative addition into the product C-Br bond. Intramolecular coupling of a vinyl bromide in the presence of an aryl iodide can take place, demonstrating unprecedented levels of selectivity.
