In the preceding paper, we described the synthesis of the vancomycin-related M(4-6)(5-7) bicyclic subunit 3 (Scheme 1),1,2 a structural motif common to all members of this family of antibiotics exemplified by vancomycin aglycon (1).3 Herein we describe the first synthesis of the vancomycin-related heptapeptide nucleus and the transformation of this intermediate to orienticin C (bis-dechlorovancomycin)
在前一篇论文中,我们描述了万古霉素相关 M(4-6)(5-7) 双环亚基 3(方案 1),1,2 的合成,这是该抗生素家族所有成员共有的结构基序,例如万古霉素苷元 (1).3 在此我们描述了万古霉素相关七肽核的首次合成以及该中间体向东方素 C(双去氯万古霉素)苷元的转化 (2).4
