heterocycles have been identified as effective directing groups (DGs) in C–H functionalization but can be retained as undesired bulky substituents in the final products. Herein, we report a Co(III)-catalyzed 1-aminoisoquinoline synthesis strategy based on oxadiazole-directed aromatic C–H coupling with alkynes and a subsequent redox-neutral C–N cyclization reaction. This labile N–O bond-based protocol
在C–H功能化中,芳香杂环已被确认为有效的导向基团(DG),但在最终产品中可保留为不希望的大取代基。在本文中,我们报告了基于乙二唑的
芳烃C–H与
炔烃偶联的Co(III)催化的
1-氨基异喹啉合成策略,以及随后的氧化还原中性C–N环化反应。这种基于N–O键的不稳定方案允许耐受各种官能团。
