dehydrogenative C–H cleaving carbonylative lactamization of 2-arylanilines promoted by visible light and potassium bases is reported. Solvent DMF acts as the sole carbonyl source in the absence of an oxidant. The irreversible release of hydrogen gas drags this reaction to the stable phenanthridinone products. This work provides a direct conversion of a broad range of 2-arylanilines to various phenanthridinones.
报道了由可见光和钾碱促进的 2-芳基苯胺的直接脱氢 C-H 裂解羰基内酰胺化。在没有氧化剂的情况下,溶剂 DMF 充当唯一的羰基来源。氢气的不可逆释放将此反应拖向稳定的菲啶酮产物。这项工作提供了将广泛的 2-芳基苯胺直接转化为各种菲啶酮的方法。该方法可应用于生物活性分子和有机光电材料的合成。
