The core moiety of several natural products referred in the literature as altechromone A can be selectively brominated or iodinated at position 3 despite the adjacent phenolic moiety. This method is extended to more elaborated 5-hydroxychromones exhibiting additional multiple bonds. halogenation - heterocycles - chromones - iodination - bromination
尽管有相邻的酚类部分,但在文献中称为altechromone A的几种天然产物的核心部分仍可以在位置3选择性溴化或碘化。该方法扩展到表现出更多多重键的更精细的5-羟基色酮。 卤化-杂环-色酮-碘化-溴化
