We present the second total synthesis of (±)-acanthodoral, a sesquiterpenoid derived from the marine nudibranch Acanthodoris nanaimoensis. Our approach involves a concise three-step transformation from a previously reported compound, resulting in the formation of a less strained precursor of the bicyclo[3.1.1]heptane core and both all-carbon quaternary stereocenters characteristic of the natural product
我们提出了 (±)-acanthodoral 的第二个全合成,这是一种源自海洋裸鳃类动物Acanthodoris nanaimoensis的倍半萜类化合物。我们的方法涉及对先前报道的化合物进行简明的三步转化,从而形成双环[3.1.1]庚烷核心的张力较小的前体以及天然产物特征的全碳四元立构中心。值得注意的是,该合成路线包含两个关键步骤:Sm(II) 诱导的 1,2-重排和半频那醇重排。
