Palladium-catalyzed weak chelation-assisted regioselective C4-arylation of indoles has been accomplished using a readily available arene at moderate temperature. The C4-arylation, weak chelating benzoyl (Bz) directing group, cross-dehydrogenative coupling (CDC), broad substrate scope, and late-stage diversifications are the important practical features.
在温和温度下,使用一种易于获得的芳烃实现了钯催化的弱螯合辅助吲哚的区域选择性C4-芳基化反应。C4-芳基化、弱螯合苯甲酰基(Bz)导向基团、交叉脱氢偶联(CDC)、广泛的底物范围和后期多样化是该反应重要的实际特点。
