A copper-catalyzed approach for the synthesis of acridones via C–Cbondcleavage and intramolecular cyclization using air as the oxidant under neutral conditions is described. This transformation offers an alternative method to prepare medicinally important acridones and a new strategy for C–Cbondcleavage.
and environmental-friendly method for the construction of acridone derivatives with isatins and arynes was described. The isatins underwent a ring expansion process oxidized by O2 in the air and a broad scope of acridones in moderate to good yields were obtained. Baeyer-Villiger-type oxidation and intermolecular-nucleophilic addition were included, and no extra oxidant except O2 was needed.
描述了一种用靛红和芳烃构建吖啶酮衍生物的简单且环保的方法。靛红经历了被空气中的 O 2氧化的扩环过程,并以中等至良好的产率获得了广泛的吖啶酮。包括Baeyer-Villiger型氧化和分子间亲核加成,除O 2外不需要额外的氧化剂。
