been developed using photoredox and H atom transfer catalysis. This C–H alkylation reaction has excellent chemoselectivity for the strong 3° C–H bonds of adamantanes in polyfunctional molecules. In substrate competition reactions, a reversal in selectivity is observed for the new H-atom transfer catalyst reported here in comparison to five known photochemical systems. Derivatization of a broad scope
已经开发出一种使用光氧化还原和H原子转移催化直接作用于类金刚石的方法。这种C–H烷基化反应对多官能分子中金刚烷的3°C–H强键具有出色的化学选择性。在底物竞争反应中,与五个已知的光化学体系相比,本文报道的新型H原子转移催化剂的选择性发生了逆转。广泛范围的类金刚石和含金刚烷类药物的衍生化突出了这种C–H功能化策略的多功能性和官能团耐受性。
