An iron‐catalyzed denitrogenative rearrangement of 1,2,3,4‐tetrazole is developed over the competitive C(sp3)–H amination. This catalytic rearrangement reaction follows an unprecedented metalloradical activation mechanism. Employing the developed method, a wide number of complex‐N‐heterocyclic product classes have been accessed. The synthetic utility of this radical activation method is showcased with
在竞争性的C(sp 3)–H胺化反应中,形成了铁催化的1,2,3,4-四唑脱氮重排。这种催化重排反应遵循前所未有的金属铁活化机理。使用已开发的方法,已经访问了许多复杂的N杂环产品类别。这种自由基活化方法的合成实用性通过生物活性分子的短合成得以展示。总的来说,这一发现强调了自由基激活策略的进展,该策略应在药物化学,药物发现和天然产物合成研究的角度得到广泛应用。
