The isolation, characterization, and total synthesis of the macrocyclic polyene mangrolide D is reported. A 16-step total synthesis relies on robust Suzuki and ring-closing metathesis reactions, and an iron-catalyzed hydroazidation of an exomethylene substituted tetrahydropyran as a key step for the synthesis of the appended 4- epi-vancosamine sugar. Although mangrolide D did not display antibiotic
报道了大环多烯芒果苷D的分离,表征和全合成。16个步骤的总合成依赖于强大的Suzuki和闭环复分解反应,并且铁催化的exomethyl取代的四氢吡喃的加氢叠氮反应是合成附加的4- Epi-vancosamine糖的关键步骤。尽管Mangrolide D没有显示抗生素活性,但这项工作应证明能够合成具有几乎相同的大环骨架的抗结核性天花霉素。
