A formal cycloaddition reaction for the synthesis of biologically and pharmaceutically important carbazolequinones via the annulation of aminoquinones with arynes has been developed. This practical and metal-free cascade reaction proceeds through successive C-C/C-N bond formations. Moreover, this novel method has been utilized for the concise synthesis of bioactive murrayaquinone A and koeniginequinone B and their analogues.
通过芳基炔与氨基喹啉的环加成反应,开发了一种用于合成具有生物和药物重要性的咔唑醌的正规环加成反应。该实用且无金属的级联反应通过连续的 C-C/C-N 键形成进行。此外,该新方法已用于生物活性的 murrayaquinone A 和 koeniginequinone B 及其类似物的简洁合成。
