synthesis of (-)-flustramine B was achieved via one-pot intramolecular Ullmann coupling and Claisen rearrangement. A striking feature of this method of synthesis is that the sequential intramolecular Ullmann coupling and Claisen rearrangement reactions proceeds with concomitant deprotection of the methoxymethyl (MOM) group to afford spirocyclic oxindole with perfect asymmetric transmission in good overall
- (-)-flustramine B 的全合成是通过一锅分子内 Ullmann 偶联和 Claisen 重排实现的。这种合成方法的一个显着特征是,顺序的分子内 Ullmann 偶联和 Claisen 重排反应伴随着甲氧基甲基 (MOM) 基团的脱保护进行,从而以良好的总产率提供具有完美不对称传输的螺环羟吲哚。
