Gambierol, a representative of the marine ladder toxin family, consists of eight ether rings, 18 stereocenters, and two challenging pyranyl rings having methyl groups that are in a 1,3-diaxial orientation to one another. Herein we describe the generation of gambierol's A-C and F-H ring systems and demonstrate the versatility of the glycosyl anhydride, enol ether-olefin RCM strategy to fused polycyclic
甘比罗尔(Gambierol)是海洋梯形毒素家族的代表,由八个醚环,18个立体中心和两个具有挑战性的吡喃基环组成,这些环具有彼此成1,3双轴取向的甲基。在本文中,我们描述了甘氨醇的AC和FH环系统的产生,并展示了糖基酸酐,烯醇醚-烯烃RCM策略对稠合多环醚的多功能性。这项工作不仅使我们能够生成足够数量的甘比罗尔前体,而且使我们能够更好地理解对于这些努力至关重要的化学转化。基础工作包括对C-糖苷和C-酮苷的研究,克莱森重排以及烯醇醚-烯烃RCM反应。
