The total synthesis of cytotoxic meroditerpenoid naphthoquinone derivative chabrolonaphthoquinone B (1) in an enantiospecific manner is divulged using a chiral pool approach. The key step of our synthetic route is a modifiedJuliaolefination between a sulfone-bearing aliphatic fragment and a Diels–Alder-derived aromatic aldehyde, leading to the stereoselective construction of the E-trisubstituted
使用手性池方法揭示了以对映体特异性方式全合成的细胞毒性 meroditerpenoid 萘醌衍生物 chabrolonaphthoquinone B ( 1 )。我们合成路线的关键步骤是在带有砜的脂肪族片段和 Diels-Alder 衍生的芳香醛之间进行修饰的 Julia 烯化,从而导致E-三取代双键的立体选择性构建。
