The total synthesis of stevastelin B3, stevastelin C3 and 5-deoxy derivative of stevastelin C3, novel 13-membered cyclic depsipeptides, is described. This study unambiguously confirmed the proposed absolute structure of stevastelin B3, and revealed that the structure of stevastelin C3 is incorrect. The correct structure of stevastelin C3 was established by the total synthesis to be 5-deoxy derivative
描述了stevastelin B3,stevastelin C3和stevastelin C3的5-脱氧衍生物(新型的13元环状双酚肽)的总合成。这项研究明确证实了拟议的Stevastelin B3的绝对结构,并揭示Stevastelin C3的结构是不正确的。通过全部合成,可以确定Stevastelin C3的正确结构是所提出结构的5-脱氧衍生物。
