A photoinduced cascade strategy leading to a variety of differentially functionalised nitriles and ketones has been developed. These reactions rely on the oxidative generation of iminyl radicals from simple oximes. Radical transposition by C(sp3 )-(sp3 ) and C(sp3 )-H bond cleavage gives access to distal carbon radicals that undergo SH 2 functionalisations. These mild, visible-light-mediated procedures
已经开发出一种光诱导级联策略,可产生多种不同功能化的腈和酮。这些反应依赖于简单肟氧化生成亚氨基自由基。通过 C(sp3 )-(sp3 ) 和 C(sp3 )-H 键断裂进行的自由基转座可接触到进行 SH 2 官能化的远端碳自由基。这些温和的可见光介导的程序可用于远程氟化、氯化和叠氮化,并应用于生物活性和结构复杂分子的修饰。
