Herein, a simple protocol has been outlined for visible-light-induced dearomative amidation reaction of phenol derivatives to afford spirolactams with broad substrate scope. The amidation was found to proceed smoothly without any photocatalyst at room temperature, and the desired spirolactams were obtained in 23%–87% yields. showed good functional-group tolerance and a broad substrate scope
在此,概述了可见光诱导苯酚衍生物脱芳酰胺化反应的简单方案,以提供具有广泛底物范围的螺内酰胺。研究发现,酰胺化反应在室温下无需任何光催化剂即可顺利进行,并以 23%–87% 的产率获得了所需的螺内酰胺。显示出良好的官能团耐受性和广泛的底物范围
