The development of a general, mild, and functional-group-tolerant direct functionalization of N-heteroarenes by C–H functionalization with N-protected amines, including azetidines under Minisci-mediated photoredox conditions, is reported. A broad scope of substituted azetidines, including spirocyclic derivatives, and heterocycles were explored. This reaction enables the production of sp3-rich complex
据报道,在Minisci介导的光氧化还原条件下,通过N-保护的胺(包括氮杂环丁烷)的C–H官能化,可以开发出对N-杂芳烃具有一般性,温和性和耐受性的功能。探索了广泛的取代氮杂环丁烷,包括螺环衍生物和杂环。该反应能够一步一步由未活化的原料胺和杂环产生富含sp3的复杂药物样结构。
