Polysubstituted indoles are prevalent in pharmaceuticals, agrochemicals, and organic materials. Presented herein is the fact that polyfunctionalized indoles can be efficiently constructed from easily accessible oxime esters and aryl iodides, involving a palladium/norbornene synergistic synthesis. The reaction is enabled by a unique class of electrophiles in palladium/norbornene cooperative catalysis
多取代吲哚普遍存在于药物、农用化学品和有机材料中。本文提出的事实是,多官能化吲哚可以由容易获得的肟酯和芳基碘化物有效构建,包括钯/降冰片烯协同合成。该反应是由钯/降冰片烯协同催化中的一类独特的亲电子试剂实现的,它们是从简单的酮衍生的肟酯。广泛的底物范围和高官能团耐受性使该方法对合成多取代吲哚具有吸引力。
