established, based on which a novel route for scutellarin derivatives preparation has been devised. The developed strategies, among which the stepwise deprotection process was also included, guarantee the high whole synthetic efficiency, and definitely will find broad application in diversity-oriented synthesis of bioactive flavonoid glycosides.
直接金葡糖醛酸键形成的一般协议,其特征在于Au(I)催化的受适当保护的葡糖醛酸基邻炔基苯甲酸酯参与的糖基化反应,以及一种简便的方法,可轻松获得黄cut苷,其通过硼酸化-氧化作用温和有效地安装在羟基上已经建立了黄烷酮衍生物的序列,在此基础上,设计了一种新的制备黄cut苷衍生物的途径。所开发的策略(其中还包括逐步脱保护过程)确保了较高的整体合成效率,并且肯定会在面向生物活性的类黄酮糖苷的多样性合成中得到广泛应用。
