This report describes the first application of a cyclobutanol ring-opening procedure in the Catellani termination reaction, which includes two β-carbon elimination processes. This tandem reaction features mild conditions, high yields, good functional group tolerance, and a broad substrate scope. Meanwhile, four types of electrophiles (N-benzoyloxyamines, alkyl iodides, aryl bromides, and benzyl chlorides) are quite compatible with this termination reaction for the construction of various types of polysubstituted aromatic hydrocarbons.

环丁醇C–C裂解烷基化终止的Catellani反应

该报告描述了在Catellani终止反应中首次应用环丁醇开环程序，该程序包括两个β-碳消除过程。该串联反应具有温和的条件，高收率，良好的官能团耐受性和广泛的底物范围。同时，四种类型的亲电试剂（N-苯甲酰氧基胺，烷基碘，芳基溴化物和苄基氯）与这种终止反应完全相容，可用于构建各种类型的多取代芳烃。
