Herein, an efficient route to amides from aldimines via aza-Breslow intermediates through aerobic oxidative carbene catalysis with LiCl as a cooperative Lewis acid is described. Many of the obtained N-heteroarylamides feature biological activity. Ambient air was used as the sole oxidant and source of oxygen in this catalytically oxidative amidation. This method allows for a broad substrate scope and
在本文中,描述了一种有效的路线,该路线从醛亚胺经由氮杂-布雷斯洛中间体通过需氧氧化卡宾催化,并以LiCl作为协同路易斯酸,进行好氧路线。许多获得的N-杂芳基酰胺具有生物学活性。在该催化氧化酰胺化反应中,环境空气被用作唯一的氧化剂和氧气源。该方法允许广泛的基材范围和温和的条件。分离了氮杂-Breslow中间体衍生物,并确认了其晶体结构。
