Abstract

Radically changing benzyls: An efficient method for the benzylarylation of activated alkenes has been developed through a copper-catalyzed tandem radical addition/cyclization strategy (see scheme). This oxidative coupling between acrylamides and benzylic hydrocarbons provides access to diverse alkyl-substituted oxindoles in good to excellent yields. A variety of functional groups were tolerated in this transformation (TBPB = tert-butylperoxy benzoate).

摘要

自由基诱导的苄基化反应

通过铜催化的串联自由基加成/环化策略,开发了一种高效的烯丙基芳烃苄基化方法(见方案)。该方法实现了丙烯酰胺和苄基型烃之间的氧化偶联,以良好至优秀的收率得到了多种烷基取代的色酮。该转化可耐受多种官能团(TBPB = 过氧化苯甲酸叔丁酯)。
