The invention is related to anti-viral compounds, compositions containing such compounds, and therapeutic methods that include the administration of such compounds, as well as to processes and intermediates useful for preparing such compounds.
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。
