(-)-Cylindricine C has been synthesized from commercially available (S)-(-)-1,2,4-butanetriol in 11 steps with an overall yield of 12%. The key step utilizes a CrCl2 reduction of an azide to form the corresponding amine with a subsequent double Michael addition to create the tricyclic skeleton of cylindricine from a monocyclic substrate.
(-)-Cylindricine C 通过从商购的 (S)-(-)-1,2,4-butanetriol 开始,在 11 步反应中成功合成,总产率为 12%。关键步骤采用了 CrCl₂ 还原叠氮化物以生成相应的胺,随后进行双迈克尔加成,以从单环底物中构建 cylindricine 的三环骨架。
