C–H activation offers huge potential in the generation of complex structures from simple starting materials. Herein we report the development of a highly diastereoselective palladium(II) catalyzed C–H functionalization cascade to produce novel, unsaturated polyheterocycles from simple diene-tethered heterocyclic starting materials. The reaction is applicable to both indole and pyrrole based substrates
C–H活化在从简单的起始原料生成复杂结构方面提供了巨大的潜力。在本文中,我们报道了由非对映选择性的钯(II)催化的C–H官能化级联反应的发展,该反应由简单的由二烯系链的杂环原料生产出新颖的,不饱和的多杂环。该反应适用于基于吲哚和吡咯的底物,并能耐受杂芳族核周围的各种官能团取代。多杂环产物形成为单一的非对映异构体,并且在一个步骤中形成了两个新的立体中心。
