Jatrophane diterpenes are structurally intriguing natural products with promising biological properties. Herein, the synthesis of the western fragment of the Euphorbiaceae constituent Pl-3 starting from (1R,5S)-bicyclo[3.2.0]hept-2-en-6-one is described. Key steps in the sequence include a Baeyer–Villiger oxidation, an iodolactonization reaction, and the installation of the northern side chain through
麻风树二萜是结构有趣的天然产物,具有良好的生物学特性。在此,描述了从 (1R,5S)-双环 [3.2.0]hept-2-en-6-one 开始合成大戟科成分 Pl-3 的西方片段。该序列中的关键步骤包括 Baeyer-Villiger 氧化、碘内酯化反应以及通过添加锂化乙烯基溴来安装北侧链。通过利用潜在对称性提高了路线的整体效率。
