The synthesis of the C1–C18 fragment of the myxobacteria metabolite rhizopodin is described. Initial attempts at installing the E,E-diene via cross coupling with an oxazole fragment gave poor results. An alternative approach, in which the diene was formed prior and the oxazole introduced by an acylation/O,N-shift protocol, gave the C1–C18 fragment 2 of rhizopodin (1).
描述了粘细菌代谢产物根硫菌素的C1-C18片段的合成。通过与恶唑片段的交叉偶联来安装E,E-二烯的最初尝试给出了较差的结果。另一种方法是先形成二烯,然后通过酰化/ O,N-转移方案引入恶唑,得到根瘤菌素的C1–C18片段2(1)。
