A first generation synthesis of 22 is described constituting the first disclosure of the preparation of an appropriately protected and fully functionalized vancomycin CDE ring system complete with the C and E ring monochloro substitution pattern. The approach, which is based on two aromatic nucleophilic substitution reactions for sequential CD and DE macrocyclization, provided the opportunity to define
描述了22的第一代合成物,构成了具有C和E环一氯取代模式的适当保护和完全官能化的万古霉素CDE环系统的制备的第一个公开内容。该方法基于连续的CD和DE大环化的两个芳香族亲核取代反应,提供了通过定义DE与未改变的CD环系统的选择性热平衡来间接控制CDE阻转异构体立体化学的机会。它的成功为CD和DE铃声系统的引入提供了首选顺序的理由。
