intermolecular oxidative coupling of imidazo[1,2-a]pyridines with alkenes was successfully developed. The scope and limitations of the reaction were further studied by using various alkenes. This method provides a ‘green’ route to 3-alkenylimidazo[1,2-a]pyridine derivatives in high yields. palladium/copper-catalyzed oxidative coupling - alkenylation - imidazo[1,2-a]pyridines
成功开发了一种新型的直接和区域选择性的Pd / Cu催化的咪唑并[1,2- a ]吡啶与烯烃的分子间氧化偶联。通过使用各种烯烃进一步研究了反应的范围和局限性。该方法提供了高收率的3-烯基咪唑并[1,2- a ]吡啶衍生物的“绿色”路线。 钯/铜催化的氧化偶合-烯基化-咪唑并[1,2- a ]吡啶
