applications. Herein, we report photocatalytic HAT-induced α-C(sp3)–H phosphonylation of aliphatic amines, providing rapid access to structurally diverse α-aminophosphonates from abundant amines. Leveraging intramolecular HAT, radical polar crossover, and an Arbuzov-type phosphonylation cascade, the challenges associated with HAT-induced C(sp3)–H to C(sp3)–P transformation were overcome. This protocol features
尽管在光催化氢原子转移(HAT)诱导的C(sp 3 )–H功能化方面取得了显着进展,实现了C(sp 3 )–H到C(sp 3 )–H 膦酰化,从而可以从丰富的胺中快速获得结构多样的 α-氨基膦酸酯。利用分子内 HAT、自由基极性交换和 Arbuzov 型磷酸化级联,解决与 HAT 诱导的 C(sp 3 )–H 到 C(sp 3 )–P 相关的挑战转型被克服了。该方案具有无碱、氧化还原中性、条件温和、适用范围广的特点,采用胺作为限制试剂,并允许对具有胺部分的复杂药物分子进行后期磷酸化。
