2,8-dioxabicyclo[3.2.1]octane core structure of zaragozic acids, inhibitors of the enzyme squalene synthase, has been achieved by exploiting the sequence of rhodium(II)-mediated intramolecular carbonyl ylide formation from an α-diazo ester and stereocontrolled 1,3-dipolar cycloaddition with (E)-3-hexene-2,5-dione.
通过利用铑(II)介导的分子内羰基叶立德形成的序列,已成功构建了一种新的高效结构的壬二酸的2,8-二氧杂双环[3.2.1]辛烷核心结构,角鲨烯合酶的抑制剂。 α-重氮酯和(E)-3-己烯-2,5-二酮与立体控制的1,3-偶极环加成反应。
