芳烃的直接催化 C-H 胺化是一种强大的合成策略,在药物、农用化学品和材料化学中具有有用的应用。尽管催化 C-H 官能化取得了进展,但脂肪胺偶联伙伴的使用仍然有限。本文描述的是使用伯胺,通过吖啶鎓光氧化还原催化剂在有氧气氛下直接 C-H 官能化来构建 C-N 键。多种伯胺,包括氨基酸和更复杂的胺,都是有效的偶联伙伴。各种富电子芳族化合物和杂芳族化合物以及复杂的生物活性芳烃都是该反应中有用的支架。我们还描述了将不被吖啶鎓催化剂氧化的芳烃(例如苯和甲苯)官能化的能力,从而负载反应性胺阳离子自由基中间体。
The direct catalytic C–H amination of arenes is a powerful synthetic strategy with useful applications in pharmaceuticals, agrochemicals, and materials chemistry. Despite the advances in catalytic C–H functionalization, the use of aliphatic amine coupling partners is limited. Described herein is the construction of C–N bonds, using primary amines, by direct C–H functionalization with an acridinium photoredox catalyst under an aerobic atmosphere. A wide variety of primary amines, including amino acids and more complex amines are competent coupling partners. Various electron-rich aromatics and heteroaromatics are useful scaffolds in this reaction, as are complex, biologically active arenes. We also describe the ability to functionalize arenes that are not oxidized by an acridinium catalyst, such as benzene and toluene, thus supporting a reactive amine cation radical intermediate.
