A method for constructing a phenanthridinone skeleton frequently found in bioactive substances without using transition metals was developed. This reaction proceeds through photooxidative C–H amidation with visible light irradiation, and commercially available organophotocatalyst. Using this synthetic method phenanthridinones are afforded under mild conditions at low cost.
开发了一种在不使用过渡金属的情况下构建在生物活性物质中经常发现的菲咯烷酮骨架的方法。该反应通过可见光辐射下的光氧化CH酰胺化反应和市售的有机光催化剂进行。使用该合成方法,在温和条件下以低成本提供了菲啶酮。
