coupling reaction were the key steps in the synthesis of precursor 1 of the aglycon of vancomycin, which already contains the complete skeleton of the target compound. The cleavage of the triazene unit from the D ring and the removal of the other protecting groups led to the aglycon of vancomycin. These strategies should be particularly valuable for the synthesis of other naturally occurring glycopeptide
构建复杂的联芳基醚的基于三氮烯的合成策略和Suzuki偶联反应是万古霉素糖苷配基前体1合成的关键步骤,万古霉素的糖苷配基前体1已包含目标化合物的完整骨架。三氮烯单元从D环上的裂解和其他保护基的去除导致万古霉素的糖苷配基。这些策略对于合成其他天然存在的糖肽抗生素应特别有价值,并为化学研究中的万古霉素家族化合物组合文库的合成提供了机会。
