Herein, we have successfully developed an efficient protocol for the construction of benzothio(seleno)phenes and indoles through an Ag‐mediated cyclization/demethylation process. Various 2‐substituted benzothio(seleno)phenes and indoles were obtained in good to excellent yields under mild reaction conditions with low catalyst loading. A conceivable reaction mechanism was proposed and supported by an
在这里,我们已经成功地开发了一种通过Ag介导的环化/去甲基化过程来构建苯并
硫代(
硒基)苯和
吲哚的有效方案。在温和的反应条件下,以较低的催化剂负载量,获得了各种优良的产率,获得了各种2-取代的苯并
