N-dealkylation of tertiary amines via photoredox catalysis and its application in late-stage functionalization. Using the developed method, more than 30 diverse aliphatic, aniline-type, and complex substrates are shown to undergo N-dealkylation, providing a method with broader functional group tolerance compared to methods found in the literature. The scope also includes tertiary and secondary amine molecules
本文介绍了一种通过光氧化还原催化叔胺N-脱烷基化的温和方法的开发及其在后期功能化中的应用。使用所开发的方法,超过 30 种不同的脂肪族、苯胺型和复杂底物被证明可以进行N-脱烷基化,与文献中的方法相比,提供了一种具有更广泛官能团耐受性的方法。该范围还包括具有复杂子结构和药物底物的叔胺和仲胺分子。有趣的是,在几个环状子结构中观察到亚胺的α-氧化而不是N-脱烷基化,这表明亚胺是相关的反应中间体。
