We report a redox-neutral P(O)–N coupling reaction of P(O)–H compounds with azides via photoredox and copper catalysis, providing new access to useful phosphinamides, phosphonamides, and phosphoramides. This transformation tolerates a wide range of nucleophilic functionalities including alcohol and amine nucleophiles, which makes up for the deficiency of classical nitrogen nucleophilic substitution
我们报道了P(O)-H化合物与叠氮化物通过光氧化还原和铜催化的氧化还原中性P(O)-N偶联反应,提供了获得有用的次膦酰胺,膦酰胺和磷酰胺的新途径。这种转化可耐受多种亲核功能,包括醇和胺亲核,这弥补了传统氮亲核取代反应的不足。为了证明这种新方法的广泛潜在应用,已开发了多种含叠氮基天然产物和药物分子的后期功能化,初步的不对称反应和连续的可见光光流过程。
