We report herein the synthesis of isoquinolines through a copper(I)-catalyzed domino reaction. During this transformation, three molecules of terminal alkynes, 2-bromoaryl aldehydes (ketones), and acetamide react together, in a sequence including Sonogashira coupling, condensation, 6-endo-dig cyclization, elimination of acetic acid, and hydrolysis. In this reaction, isoquinolines with broad functional
我们在此报告通过铜 (I) 催化的多米诺骨牌反应合成异喹啉。在此转化过程中,末端炔烃、2-溴芳基醛(酮)和乙酰胺的三个分子一起反应,顺序包括 Sonogashira 偶联、缩合、6-endo-dig 环化、乙酸消除和水解。在该反应中,以乙酰胺为氮源,成功获得了具有广泛官能团耐受性的异喹啉,为有味和有毒的胺提供了替代品。
