novel palladium- and copper-catalyzed one-pot multicomponent synthesis of hetero α,α′-dimers of heterocycles via Sonogashira coupling and double cyclization cascade involving imine formation has been developed. This reaction cascade proceeded under mild conditions, providing a powerful synthetic tool for the assembly of π-conjugated systems with a combination of palladium-catalyzed post-direct C–H bond
通过Sonogashira偶联和涉及亚胺形成的双环化级联反应,开发了一种新颖的钯和铜催化一锅多环合成杂环杂α,α'-二聚体的方法。该反应级联反应在温和的条件下进行,为结合钯催化的直接C-H键芳基化后的π-共轭体系的组装提供了强大的合成工具。
