copper-catalyzed multicomponent coupling reaction of primary aromatic amines, rongalite, and alkynes for the direct synthesis of N-aryl propargylamines has been developed. This method could overcome the substrate limitation in A3 coupling reactions of primary aromatic amines, formaldehyde, and alkynes. Mechanistic studies revealed that rongalite acts as not only the active C1 unit but also the accelerator
在这项工作中,开发了一种实用的铜催化的芳香伯胺、雕白粉和炔烃的多组分偶联反应,用于直接合成N-芳基炔丙胺。该方法可以克服芳香伯胺、甲醛和炔烃的A 3偶联反应中底物的限制。机理研究表明,雕白粉不仅充当活性C1单元,而且还是活化原位生成的N-芳基甲亚胺与炔烃偶联反应的促进剂。该偶联反应效率高,底物范围广,可用于放大合成和将相应的产物N-芳基炔丙胺转化为有用的杂环骨架。
