  Synthesis of O-Me Ulongamide B and O-Me Ulongamide C, Natural Modified Cyclodepsipeptides

  摘要：

  Synthesis of O-Me ulongamide B and O-Me ulongamide C, modified natural cyclodepsipeptides, was achieved by a convergent route. The respective dipeptides and tridepsipeptides were coupled, obtaining linear depsipentapeptides, which were then deprotected and cyclized. These compounds were tested against three different types of human carcinoma cells and showed only moderate activity.

  A total synthesis of ulongamide A (1), a cytotoxic natural cyclic depsipeptide, was achieved by a convergent route involving coupling of the fragments 7 and 8 to the pentapeptide 24, and subsequent cyclization thereof after prior removal of the t-Boc protecting groups.

  ulongamide A（1）是一种具有细胞毒性的天然环状二肽肽，是通过一条收敛性路线实现的，该路线涉及将片段7和8与五肽24偶联，然后在先去除t- Boc保护基团之后将其环化。
