The rapid construction of phenalenes through the reaction of 8-alkynyltetralones with Fischer–carbene complexes followed by either an inter- or intra-molecular Diels–Alder reaction is presented. As a showcase of the synthetic utility of this process, the rapid construction of polycyclic ring systems containing the tetracycline core has been demonstrated through an iterative application of this reaction
介绍了通过 8-炔基四氢萘酮与 Fischer-carbene 配合物的反应,然后是分子间或分子内 Diels-Alder 反应快速构建苯酚。作为该过程合成效用的展示,已通过该反应序列的迭代应用证明了包含四环素核心的多环环系统的快速构建。
