A short synthesis of the calicheamicin oligosaccharide is reported. All the glycosidic linkages have been constructed using the sulfoxide glycosylation reaction, demonstrating the efficacy of the method. A general method to introduce N-O glycosidic linkages in oligosaccharides has been developed and employed to construct the N-O bond that connects rings A and B. In the final step of the synthesis,
报道了加利车霉素寡糖的短合成。所有糖苷键均使用亚砜糖基化反应构建,证明了该方法的有效性。已开发出一种在寡糖中引入 NO 糖苷键的通用方法,并用于构建连接环 A 和 B 的 NO 键。在合成的最后一步,加利车霉素寡糖的两半以完全脱保护的形式偶联。这种会聚合成允许快速构建加利车霉素寡糖的衍生物,以测试特定结构特征在 DNA 结合中的重要性
