  Pd-Catalyzed Intramolecular Oxidative C–H Amination: Synthesis of Carbazoles

  摘要：

  A Pd-catalyzed oxidative C-H amination of N-Ts-2-arylanilines under ambient temperature using Ozone as an inexpensive, safe, and easy-to-handle oxidant has been developed. This process represents a green and practical method for the facile construction of carbazoles with a broad substrate scope and wide functional group tolerance.

  one-pot procedure for the catalytic preparation of the biologically interesting class of carbazoles. The new procedure is based on the combined catalysis of palladium and norbornene starting from o-substituted iodoarenes and N-sulfonylated or N-acetylated o-bromoanilines. A well-known member of this class, carbazomycin A, has been successfully prepared.

  involving sequential nucleophilic and electrophilic C–N bond formations. Herein, we report a novel Suzuki reaction/C–H activation/amination sequence for building a myriad of carbazoles in a single transformation using bifunctional secondary hydroxylamines. It is noteworthy that the synthetic utility of this methodology is highlighted by the total synthesis of clausine V and glycoborine by incorporating

  使用羟胺衍生物作为单一氮源来制备 N-杂环分子的传统方法依赖于涉及连续亲核和亲电 C-N 键形成的两个化学过程。在此，我们报告了一种新颖的铃木反应/C-H活化/胺化序列，用于使用双功能仲羟胺在一次转化中构建无数咔唑。值得注意的是，通过将标题[2 + 2 + 1]环胺化作为关键步骤，克劳辛V和糖硼烷的全合成突出了该方法的合成效用。进行对照实验以更好地了解反应机理。
