The first, diastereoselective total syntheses of musellarins A-C were achieved concisely with 7.8-9.8% yields in 15-16 steps. The key synthetic features include (i) an Achmatowicz rearrangement, Kishi reduction, and Friedel-Crafts cyclization to construct the tricyclic framework and (ii) Heck coupling of aryldiazonium salts to introduce the aryl group into the dihydropyran in a 2,6-trans fashion in
以15-16个步骤的7.8-9.8%的收率,简明地实现了musellarins AC的第一个非对映选择性总合成。关键的合成特征包括(i)Achmatowicz重排,Kishi还原和Friedel-Crafts环化以构建三环骨架,以及(ii)芳基重氮盐的Heck偶联,以2,6-反式的方式将芳基引入二氢吡喃中在合成的最后阶段。
