(+)-Cladospolide C was synthesized in eight steps with 5% total yield, using methyl acrylate, (3R, 4R)-1,5-hexadiene-3,4-diol, and (6R)-6-hepten-2-ol as the starting materials. Two cross-metathesis reactions and Yamaguchi esterification were applied to assemble the three units into (+)-Cladospolide C. Unsuccessful routes using ring-closing metathesis are also discussed.
(+)Cladospolide C 通过八步反应合成,总收率为 5%,采用甲基丙烯酸酯、(3R,4R)-1,5-己二烯-3,4-二醇和 (6R)-6-庚烯-2-醇作为起始原料。通过两次交叉-转移反应和山口酯化反应,将这三个单元组装形成 (+)-Cladospolide C。此外,还讨论了使用环闭转移反应但未能成功的合成路线。
