(DMOA)‐derived meroterpenoid scaffolds has yet to be reported despite great interest from the chemistry and biomedical research communities. A concise synthetic route with the potential to access DMOA‐derived meroterpenoids is highly desirable to create a library of related compounds. Herein, we report novel dearomatization methodology followed by polyene cyclization to access DMOA‐derived meroterpenoid frameworks
尽管化学和生物医学研究界对此表现出极大的兴趣,但法呢基焦磷酸和二甲基奥西林酸(DMOA)衍生的类萜支架的仿生途径尚未有报道。非常需要一条简洁的合成路线,有可能获得 DMOA 衍生的类萜,以创建相关化合物库。在此,我们报告了一种新颖的脱芳构化方法,然后进行多烯环化,通过六个步骤从市售起始材料中获得 DMOA 衍生的半萜类框架。此外,几种法尼基烯烃底物被用来生成结构新颖的、DMOA 衍生的类萜衍生物。 DFT 计算与实验相结合,为观察到的多环化产物的热力学分布提供了理论依据。
