We report herein a direct unsymmetric coupling and controllable aromatization reaction of saturated N-heterocycles enabled by synergistic photoredox and acid catalysis. The reaction furnishes C2–C3 connected biheterocycles in a highly chemo- and regioselective manner under rather mild conditions. Mechanistic studies indicated that the reaction proceeded via enamine-iminium coupling leading to exclusively
我们在本文中报道了通过协同的光氧化还原和酸催化实现的饱和N-杂环的直接不对称偶联和可控制的芳构化反应。在相当温和的条件下,该反应以高度
化学和区域选择性的方式提供了C2-C3连接的双杂环。机理研究表明,反应是通过烯胺-
亚胺偶联进行的,仅导致C2-C3连接。
