• DMSO/<i>t</i>-BuONa/O₂-Mediated Aerobic Dehydrogenation of Saturated <i>N</i>-Heterocycles
  作者：Ruchun Yang、Shusheng Yue、Wei Tan、Yongfa Xie、Hu Cai

  DOI：10.1021/acs.joc.9b03447

  日期：2020.6.5

  Aromatic N-heterocycles such as quinolines, isoquinolines, and indolines are synthesized via sodium tert-butoxide-promoted oxidative dehydrogenation of the saturated heterocycles in DMSO solution. This reaction proceeds under mild reaction conditions and has a good functional group tolerance. Mechanistic studies suggest a radical pathway involving hydrogen abstraction of dimsyl radicals from the N–H

  芳族N-杂环如喹啉，异喹啉和二氢吲哚是通过叔丁醇钠促进的DMSO溶液中饱和杂环的氧化脱氢而合成的。该反应在温和的反应条件下进行并且具有良好的官能团耐受性。机理研究表明，一种自由基途径涉及从底物的N–H键或α–C–H夺取二甲基自由基的氢以及随后氮或α-氨基烷基自由基的氧化。

  Quinoline synthesis from easily accessible raw materials such as anilines is a valuable and meaningful task. Herein, we communicate an iodide‐ and silver‐mediated C−H/C−H oxidative annulation–aromatization between anilines and allyl alcohols. This protocol provides a direct route to the synthesis of quinoline derivatives from inexpensive commodities. Various kinds of anilines, even heterocyclic anilines

  由苯胺等容易获得的原料合成喹啉是一项宝贵而有意义的任务。在本文中，我们传达了苯胺和烯丙醇之间碘化物和银介导的CH / CH氧化环化-芳香化反应。该协议提供了从廉价商品合成喹啉衍生物的直接途径。各种苯胺，甚至杂环苯胺，都是可行的底物，可产生高收率的相应多取代喹啉。
