  methods for the introduction of CF2H into heteroarenes. Herein we disclose a new strategy for the direct introduction of a difluoromethyl group into heteroarenes via the copper-mediated C-H oxidative difluoromethylation of heteroarenes with TMSCF2H. This mild and regioselective method enables the convenient synthesis of a range of difluoromethylated heteroarenes in high yields. The usage of 9,10-phenanthrenequinone

  二氟甲基 (CF2H) 在药物化学领域具有重要意义。然而，由于将 CF2H 引入杂芳烃的合成方法的限制，对含有该基团的分子支架的研究受到了阻碍。在此，我们公开了一种通过铜介导的 CH 氧化二氟甲基化杂芳烃与 TMSCF2H 将二氟甲基直接引入杂芳烃的新策略。这种温和且具有区域选择性的方法能够以高产率方便地合成一系列二氟甲基化杂芳烃。使用 9,10-菲醌 (PQ) 作为氧化剂对于这种新的二氟甲基化反应的成功至关重要。
