orthogonal cascade CH functionalization processes are described, based on ruthenium‐catalyzed CH alkenylation. 1‐Indanones, indeno indenes, and indeno furanones were accessed through cascade pathways by using arylacetophenones as substrates under conditions of catalytic [Ru(p‐cymene)Cl2}2] and stoichiometric Cu(OAc)2. Each transformation uses CH functionalization methods to form CC bonds sequentially
描述了基于钌催化的C H 烯基化的三个正交级联 C H 官能化过程。在催化[Ru( p-伞花烃)Cl 2 } 2 ]和化学计量的Cu(OAc) 2条件下,使用芳基苯乙酮作为底物,通过级联途径获得1-茚满酮、茚并茚和茚并呋喃酮。每个转化均使用CH功能化方法顺序形成CC键,茚并呋喃酮合成以CO键形成为终止步骤。这项工作展示了钌催化烯基化作为平台反应开发更复杂转化的能力,在单个操作中发生多个C - H官能化步骤以获得新型碳环结构。
