Total synthesis of (−)-mniopetal E, the common skeleton of the biologically intriguing mniopetals A-D, was accomplished for the first time. The key step of the total synthesis was stereoselective intramolecular Diels-Alder reaction for construction of the octahydronaphthalene core structure. Our total synthesis as natural enantiomeric form established the unsettled absolute stereochemistry of the antibiotic
首次完成了(-)-小荆芥E的全合成,这是生物学上令人着迷的小荆芥AD的共同骨架。全合成的关键步骤是构建八氢萘核心结构的立体选择性分子内Diels-Alder反应。我们作为天然对映异构体形式的总合成建立了抗生素尚未解决的绝对立体化学。
