Total synthesis of natural product (±)-bruguierol A was accomplished in 10-steps and with an overall 16.8% yield. The embedded unique 8-oxabicyclo[3.2.1]octane core skeleton in this natural product was constructed via a novel Sc(OTf)3-catalyzed intramolecular [3+2] cycloaddition of cyclopropane, which was developed recently in this laboratory. This general synthetic strategy can be potentially applied
天然产物(±)-bruguierol A的总合成分10步完成,总收率16.8%。该天然产物中嵌入的独特的8-氧杂双环[3.2.1]辛烷核心骨架是通过新的Sc(OTf)3催化的环丙烷的分子内[3 + 2]环加成环而构建的,该环丙烷是最近在该实验室开发的。这种一般的合成策略可以潜在地应用于多种结构相关的天然产物的合成。
