Herein, we report a metal-free and step-economic synthesis of phenanthridines from 2-biarylmethanamines under mild conditions. The reaction involves iodine-supported intramolecular C–H amination and oxidation of 5,6-dihydrophenanthridine under air and benign visible light. The mechanism study reveals that visible light plays a key role in both these steps.
在这里,我们报告了在温和的条件下从2-biarylmethanamines无金属和经济的步骤合成菲啶。该反应包括碘在空气和良性可见光下的分子内CH–H胺化和5,6-二氢菲啶的氧化。机制研究表明,可见光在这两个步骤中都起着关键作用。
