The concise and step-economical total syntheses of three hydroxyaurones and one polymethoxyflavone from readily available starting materials is described. A divergent synthetic strategy is employed, which centres on a common chalcone scaffold from which both the aurone and flavone frameworks can be accessed through the use of different oxidative cyclisation methods. These are the first reported total
描述了从容易获得的起始材料中简明且经济地全合成三种羟基金黄酮和一种聚甲氧基黄酮。采用了一种不同的合成策略,该策略以常见的查耳酮支架为中心,通过使用不同的氧化环化方法,可以从该支架中获得金酮和黄酮骨架。这些是首次报道的这些具有生物学意义的化合物的全合成。
