Intramolecular hydroarylation of alkenes through hydrogen atomtransfer (HAT) represents a robust method to prepare benzo-fused heterocycles. However, the reported methods have limitations in a variety of accessible cyclic scaffolds. Here we report a dual cobalt- and photoredox-catalyzed HAT hydroarylation of alkenes that is characterized by higher efficiency in the synthesis of a δ-lactam compared
通过氢原子转移 (HAT) 对烯烃进行分子内加氢芳基化是一种制备苯并稠合杂环的可靠方法。然而,所报道的方法在各种可接近的环状支架中存在局限性。在这里,我们报告了双钴和光氧化还原催化的烯烃 HAT 氢化反应,其特点是与已建立的方案相比,合成 δ-内酰胺的效率更高。所提出的机制得到了实验和 DFT 计算的支持。
