Total synthesis of biologically interesting natural and unnatural pyranoflavones has been accomplished starting from readily available 2,4‐dihydroxyacetophenone or 2,4‐dihydroxy‐6‐methoxyacetophenone in three steps, i.e., benzopyran formation, condensation, and cyclization reaction.
从易于获得的2,4-二羟基苯乙酮或2,4-二羟基-6-甲氧基苯乙酮开始,已通过三个步骤(即苯并吡喃形成,缩合和环化反应)完成了生物学上有趣的天然和非天然吡喃类黄酮的全合成。
