The development of a de novo synthetic strategy for rapid assembly of biologically relevant multisubstituted furans is an appealing but challenging task. Herein, we disclose NHC and organophotocatalysis cocatalyzed three-component radical 1,4-diacylation/cycloisomerization cascade process of readily available 1,3-enynes, which provides an efficient and straightforward entry to a wide range of polysubstituted
开发用于快速组装生物学相关多取代呋喃的从头合成策略是一项有吸引力但具有挑战性的任务。在此,我们公开了NHC和有机光催化助催化的三组分自由基1,4-二酰基化/环异构化级联过程,该过程容易获得1,3-烯炔,该过程提供了一种有效且直接的途径来获得各种多取代呋喃,具有良好的产率和优异的区域性- 和化学选择性。该反应条件温和,底物范围广,官能团兼容性好。
