An acyclic intermediate representing a putative biomimetic precursor of the C28–C40 domain of the novel marine toxin azaspiracid was constructed convergently from C28–C34 and C35–C40 fragments. In studying the assembly of the C28–C34 dioxabicyclo[3.3.1]nonane system via an intramolecular hetero-conjugate addition upon a C34–C36 enone, a stereoselective C-Michael addition intervened to provide a highly
从C28-C34和C35-C40片段聚合地构建了一个无环中间体,该中间体代表新型海洋毒素氮杂螺菌酸C28-C40结构域的推测的仿生前体。在研究通过在C34–C36烯酮上通过分子内杂共轭加成反应来组装C28–C34二恶双环[3.3.1]壬烷系统时,立体选择性C- Michael加成反应提供了高度取代的环己烷。
