An enantioselective synthesis of the indole diterpenoid natural product paspaline is disclosed. Critical to this approach was the implementation of stereoselective desymmetrization reactions to assemble key stereocenters of the molecule. The design and execution of these tactics are described in detail, and a thorough analysis of observed outcomes is presented, ultimately providing the title compound
公开了吲哚二萜天然产物paspaline的对映选择性合成。这种方法的关键是实施立体选择性去对称反应来组装分子的关键立体中心。详细描述了这些策略的设计和执行,并对观察到的结果进行了彻底分析,最终提供了高立体纯度的标题化合物。该合成为制备该分子家族中的关键立体中心提供了一个新的模板,并且在制备 paspaline 的过程中开发的反应在制备甾族天然产物中呈现出一系列新的合成断裂。
