route to oxygenated Plakortin pentalenes is described. Along with the previously disclosed total synthesis of hippolachnin A, the potential of this scheme is demonstrated by the first total synthesis of gracilioether E, as well as the total synthesis of gracilioether F. Key features of the unified synthetic strategy include the concise construction of common key intermediate 1 and a topological-strategy
描述了到含氧的Plakortin pentalenes的统一途径。除先前公开的河马素A的全合成外,该方案的潜力还可以通过首先合成禾草醚E以及禾草醚F进行全合成来证明。该统一合成策略的关键特征包括简洁的通用结构关键中间体1和高度取代的
环丁烯的拓扑策略指导的功能化,可提供对核心骨架的有效访问。
