A concise and direct synthetic strategy for the construction of 2-aryliminochromene skeleton by cascade three-component coupling reaction of arynes, N,S-keteneacetals, and DMF in good yields has been disclosed. The process demonstrates the first example of aryne chemistry combined with N,S-keteneacetals. Using this strategy, an expeditious synthesis of biologically important arylimino-2H-chromene-3-
已经公开了通过芳烃,N,S-酮缩醛和DMF的级联三组分偶联反应以良好的产率构建2-芳基亚甲基苯胺骨架的简明而直接的合成策略。该方法证明了芳烃化学与N,S-烯酮缩醛结合的第一个例子。使用这种策略,可以快速合成生物学上重要的arilimino-2 H -chromene-3-羧酰胺。
