(+)-obtusenyne has been completed. The key steps include a Sharpless kinetic resolution and an asymmetric glycolate alkylation to establish the stereogenic centers adjacent to the ether linkage and a ring-closing metathesis reaction to construct the nine-membered ether without the aid of a cyclic conformational constraint. The synthesis was completed in 20 linear steps from commercially available 1,5-hexadiene-3-ol
laurencia 代谢物 (+)-obtusenyne 的全合成已经完成。关键步骤包括 Sharpless 动力学拆分和不对称乙醇酸酯烷基化,以建立与醚键相邻的立体中心,以及在没有环状构象约束的帮助下构建九元醚的闭环复分解反应。从市售的 1,5-己二烯-3-醇以 20 个线性步骤完成合成。
