A variety of substituted iminocoumarins are prepared in good to excellent yields via a copper-catalyzed multicomponenet reaction of sulfonyl azides, terminal alkynes, and salicylaldehydes or o-hydroxylacetophenones. The method is general, mild, versatile, and efficient. A plausible mechanism for the domino process is proposed.
通过磺酰叠氮化物、末端炔烃与水杨醛或邻羟基苯乙酮的铜催化多组分反应,以良好至优异的产率制备了多种取代亚氨基香豆素。该方法具有通用性、温和性、多功能性且高效。提出了多米诺过程的合理机制。
