The first biomimetic total syntheses of ent-nakorone, ent-durgamone, and ent-abudinol B were accomplished by combining features of tandem polyepoxide cyclization with biomimetic polyene cyclization. The present biomimetic synthesis route offers efficient access to these marine natural products. In addition, the synthesis of the tetrasubstituted alkene of ent-abudinol B demonstrates the application
ent-nakorone、ent-durgamone 和 ent-abudinol B 的首次仿生全合成是通过将串联多环氧化物环化与仿生多烯环化的特征相结合而完成的。目前的仿生合成路线为这些海洋天然产物提供了有效的途径。此外,ent-abudinol B 的四取代烯烃的合成证明了钯催化的两种不同多环酮通过相应的乙烯基三氟甲磺酸酯交叉偶联的应用,然后部分氢化所得共轭二烯。
