Synthesis of the C7-C20 subunit of amphidinolides C and F has been accomplished utilizing a Me3Al-mediated ring opening of a vinyl iodide/allylic epoxide to establish the C12,13anti stereochemistry, an organolithium coupling/olefination sequence to construct the C9-C11 diene moiety and a sulfone alkylation/hydroxylation strategy to join the C7-C14 and C15-C20 fragments.
利用 Me3Al 介导的碘乙烯/烯丙基环氧化物的开环,建立 C12,13 反立体化学,构建 C9-C11 二烯的有机锂偶联/烯化序列,完成了两栖内酯 C 和 F 的 C7-C20 亚基的合成部分和磺基烷基化/羟基化策略来连接 C7-C14 和 C15-C20 片段。
