by the “umpoled” 1,4‐dioxygenation pattern characteristic for the polyketide frame of amphidinolideF was mastered by a late‐stage ring‐closing alkyne metathesis followed by a directed transannular hydration under the aegis of a carbophilic π‐acid catalyst. This concordant strategy enabled a concise totalsynthesis of this enticing marine natural product.

An enantioselective synthesis of the C(1)–C(15) segment of the marine natural product amphidinolide C has been accomplished by a route that includes a stereoselective boron–Wittig reaction to furnish a trisubstituted alkenylboronate. In addition, the route employs enantioselective alkene diboration to install the C(6) hydroxyl group which undergoes intramolecular conjugate addition to establish a tetrahydrofuran
海洋天然产物两栖内酯 C 的 C(1)–C(15) 片段的对映选择性合成已通过包括立体选择性硼-Wittig 反应以提供三取代烯基硼酸酯的路线完成。此外,该路线采用对映选择性烯烃二硼化来安装C(6)羟基,该羟基经过分子内共轭加成形成四氢呋喃环。最后,完成催化 Suzuki-Miyaura 交叉偶联以构建 C(9)-C(10) 键。
