pharmaceuticals. Herein, we reported the first palladium-catalyzed intramolecular C-H/C-H dehydrogenative coupling reaction of two simple arenes to generate 5,6-dihydrophenanthridines. The approach features a broad substrate scope and good tolerance of functional groups, offering an efficient alternative synthesis route for important 5,6-dihydrophenanthridine compounds.
5,6-二氢菲啶是天然产物和药物中常见的氮杂杂环骨架。在此,我们报道了第一个钯催化的两种简单芳烃的分子内 CH / CH 脱氢偶联反应生成 5,6-二氢菲啶。该方法具有广泛的底物范围和良好的官能团耐受性,为重要的 5,6-二氢菲啶化合物提供了一种有效的替代合成路线。
