An efficient iodine-imine synergistic promoted Povarov-type multicomponent reaction was reported for the synthesis of a practical 2,2′-biquinoline scaffold. The tandem annulation has reconciled iodination, Kornblum oxidation, and Povarov aromatization, where the methyl group of the methyl azaarenes represents uniquely reactive input in the Povarov reaction. This method has broad substrate scope and
据报道,一种有效的碘-亚胺协同促进 Povarov 型多组分反应可用于合成实用的 2,2'-联喹啉支架。串联环化协调了碘化、Kornblum 氧化和 Povarov 芳构化,其中甲基氮杂芳烃的甲基代表 Povarov 反应中独特的反应输入。该方法底物范围广,条件温和。此外,这些 2,2'-联喹啉衍生物已直接用作金属催化反应中的二齿配体。
