• Oxadiazolone-Enabled Synthesis of Primary Azaaromatic Amines
  作者：Xiaolong Yu、Kehao Chen、Fan Yang、Shanke Zha、Jin Zhu

  DOI：10.1021/acs.orglett.6b02814

  日期：2016.10.21

  Despite their tremendous synthetic and pharmaceutical utility, primary azaaromatic amines remain elusive for access based on a generally applicable C–H functionalization strategy. An oxadiazolone-enabled approach is reported for convenient entry into N-unsubstituted 1-aminoisoquinolines through Co(III)-catalyzed redox-neutral, step-, atom-, and purification-economic C–H functionalization with alkynes

  尽管它们具有巨大的合成和制药用途，但基于普遍适用的C–H官能化策略，氮杂芳族伯胺仍然难以获得。恶二唑酮使能的方法据报道可方便地通过炔烃通过Co（III）催化的氧化还原中性，阶跃，原子和纯化经济的CHH功能化进入N-未取代的1-氨基异喹啉。甲15 Ñ标记实验揭示了两个恶二唑酮N原子作为引导位点的有效性。可以将已安装的伯胺用作合成有用的手柄，用于附接发散的附件。

  An effective method for the synthesis of fully substituted 5-sulfonamidoimidazoles by Rh(II)-catalyzed transannulation of 1,2,4-oxadiazole derivatives with N-sulfonyl-1,2,3-triazoles is reported. The reaction works well with both aromatic 1,2,4-oxadiazoles and 1,2,4-oxadiazol-5-ones providing a flexible approach to N-(alkoxy/amino)carbonyl- and N-alkyl-substituted imidazoles. Both the disclosed reactions

  Oxadiazolones are first employed as the three-atom coupling partners in the Tf2NH-catalyzed cycloaddition with ynamides. This formal [3 + 2] cycloaddition allows a rapid synthesis of aminoimidazoles with a broad substrate scope. The approach also features a metal-free catalytic cycloaddition process, which may find applications in the synthesis of bioactive molecules. Besides, the resulting N-methyl
