with N-amidopyridinium salts catalyzed by 4CzIPN under mildconditions. For imidazoheterocycles and N-amidopyridinium salts with various substituents, the reaction proceeded smoothly to give the corresponding products in moderate to good yields. The reaction provides a new strategy for the synthesis of secondary amides with the imidazo[1,2-a]pyridine core.
在温和条件下,4CzIPN 催化咪唑杂环与N-酰胺吡啶鎓盐发生可见光促进反应,合成了 C-3 酰胺化咪唑杂环。对于具有各种取代基的咪唑杂环和N-酰胺吡啶鎓盐,反应顺利进行,以中等至良好的收率得到相应的产物。该反应为以咪唑并[1,2- a ]吡啶为核心的仲酰胺的合成提供了新的策略。
