toward the total synthesis of the sesterterpenoid variecolin (1) is presented. Synthesis of the key hemiketal, containing the core ABC ring skeleton, has been achieved on a model system by an expeditious route utilizing samarium(II) iodide. Furthermore, enantioselective syntheses of component fragments for the total synthesis have been developed.
[反应:见正文]提出了一种酯化的方法,用于酯基萜烯水杨酸酯(1)的全合成。通过使用碘化sa(II)的快速路线,已在模型系统上完成了包含半核心ABC环骨架的关键半缩酮的合成。此外,已经开发了用于全合成的组分片段的对映选择性合成。
