We report the first total synthesis of the biologically active fungal natural product daldiquinone (5), which was accomplished with a longest linear sequence of 8 steps in 41% overall yield. The construction of the unsymmetrical binaphthalene core was realized by a Suzuki-Miyaura cross-coupling in 88% yield on gram scale. Oxidation of naphthol 17 with IBX afforded the key naphthoquinone intermediate
我们报告了具有生物活性的真菌天然产物 daldiquinone ( 5 ) 的首次全合成,该合成以最长的 8 步线性序列完成,总产率为 41%。通过 Suzuki-Miyaura 交叉偶联以 88% 的克级产率实现了不对称联萘核心的构建。用 IBX氧化萘酚17以高产率 (92%)提供了关键的萘醌中间体18 。
