Elansolid A属于一类聚酮大环内酯天然产物, 具有良好的抗菌活性. 已经通过28步的最长线性合成步和总共41步反应实现了elansolid A的首次全合成. 在此基础上, 提出了elansolid A的简化类似物结构, 主要包含环己基稠合的19元大环内酯单元, 并采用汇聚式合成策略, 通过酸酐的去对称化醇解、钯催化的Stille偶联、Suzuki-Miyaura偶联以及Mukaiyama环化等关键反应, 完成了此简化衍生物的不对称全合成.

关键词: 不对称全合成, 偶联反应, 简化类似物, Elansolid A

Natural product elansolid A belongs to one type of polyketide macrolactone with promising antibiotic activity. Previously, the first total synthesis of elansolid A in 28 longest linear sequence (LLS) and 41 steps in total has been achieved. Herein, the simplified analog of elansolid A, featured with a cyclohexyl-fused 19-memebered macrolactone, was proposed, and its asymmetric total synthesis based on a convergent strategy and key reactions exemplified by desymmetric alcoholysis of anhydride, Pd-catalyzed Stille coupling, Suzuki-Miyaura coupling as well as Mukaiyama macrolactonization was finished.

Key words: asymmetric total synthesis, coupling reaction, simplified analog, elansolid A
