The direct visible light-mediated C–H alkylation of heteroarenes using aliphatic carboxylic acids is reported. This mild method proceeds at low catalyst loadings (0.5 mol %) and has a high functional group tolerance and a broad substrate scope. Notably, functionalization of (iso)quinoline, pyridine, phthalazine, benzothiazole, and other heterocyclic derivatives with both cyclic and acyclic primary
据报道,使用脂肪族羧酸的直接可见光介导的杂芳烃的CH烷基化。这种温和的方法在低催化剂负载量(0.5摩尔%)下进行,并且具有较高的官能团耐受性和广泛的底物范围。值得注意的是,在室温下,在标准条件下,将(异)喹啉,吡啶,酞嗪,苯并噻唑和其他杂环衍生物与环状和非环状的伯,仲和叔羧酸以及氨基和脂肪酸一起官能化。该协议可以将丰富的原料快速转化为医学上相关的“类药物”部分。
