  Synthesis of N-Functionalized/NH-Multisubstituted Indoles, Thienopyrroles, Pyrroloindoles, and Pyrazolopyrroles via Sequential One-Pot Base-Mediated and Copper-Catalyzed Inter- and Intramolecular Amination of 2-[2-Bromo(het)aryl]-3-(het)aryl-3-(methylthio)acrylonitriles

  摘要：

  A novel, efficient route to substituted 1-N-(het)aryl/NH-2-(het)aryl-3-cyanoindoles and related pyrrolo-fused heterocycles such as thienopyrroles, pyrroloindoles, and pyrazolopyrroles has been reported. The overall protocol involves sequential cycloamination of readily available 2-[2-bromo(het)aryl]-3-(het)aryl-3-(methylthio)acrylonitrile precursors with primary amines or amides via two key C-N bond-forming processes, one base-mediated intermolecular and the other Cu-catalyzed intramolecular arylamination leading to N(1)-C(2) and N(1)-C(7a) bond formation, respectively, in a two-step one-pot procedure.

  of either palladium acetate/cupric acetate catalytic system under oxygen atmosphere or palladium acetate/silver carbonate in the presence of pivalic acid as additive. The method is compatible with a diverse range of substituents on the aryl ring as well as at the 2- and 3-positions of the indole ring. The versatility of this method was further demonstrated by elaborating it for the synthesis of heterofused

  通过分子内氧化C–H活化胺化现有的2-（杂）芳基-3-（杂）芳基/烷基-3-（杂）芳基/酰基氨基丙烯腈/烯胺酮前体，开发了一种多取代吲哚的有效途径。在氧气气氛下存在乙酸钯/乙酸铜催化体系，或在新戊酸作为添加剂的情况下存在乙酸钯/碳酸银。该方法与芳基环以及吲哚环的2-和3-位上的各种取代基兼容。详细说明了该方法的多功能性，可用于合成杂稠稠合的吡咯，如噻吩并[2,3- b ]吡咯，噻吩并[3,2- b ]吡咯，吡咯并[2,3- b ]吲哚和pyrrolo [2,3-b ]吡啶，收率高。已经提出了形成这些吲哚的可能机理。
