The 6, 6, 7-membered tricyclic ether ring system (ABC-ring) of hemibrevetoxin B was stereoselectively synthesized. The curcial steps in the present synthesis involve the ring expansion of tetrahydropyran to oxepane, 6-endo cyclization of epoxy alcohol, and insertion of a C-4 unit to the A-ring.
hemibrevetoxin B 的 6, 6, 7 元三环醚环系统 (ABC-ring) 是立体选择性合成的。本合成中的关键步骤包括四氢吡喃扩环为氧杂环庚烷、环氧醇的 6-内环化以及将 C-4 单元插入 A 环。
