key reaction in a model sequence for the total synthesis produced two structurally divergent products, both were converted to the same advanced model intermediate that contains the complete carbon skeleton and (except for the extraneous oxygen substituent in the model series) the functional group pattern of the griseusins.
[反应:见正文] 芳基 C-糖苷全合成的“反向极性”或“umpolung”策略是在抗生素 (-)-griseusin B 的背景下开发的。全合成产生了两种结构不同的产品,两者都被转化为相同的高级模型中间体,其中包含完整的碳骨架和(模型系列中的外来氧取代基)灰色素的官能团模式。
