  • Synthesis of vulpinic and pulvinic acids from tetronic acid
    作者:Yann Bourdreux、Ewen Bodio、Catherine Willis、Célia Billaud、Thierry Le Gall、Charles Mioskowski
    DOI:10.1016/j.tet.2008.06.058
    日期:2008.9
    A common precursor, tetronic acid, was used in the synthesis of several vulpinic acids and pulvinic acids, which are pigments found in several lichens and mushrooms. The key features of this method are a two-step alkylidenation of benzyl tetronate and a Suzuki–Miyaura cross-coupling. The synthesis of several natural products, vulpinic acid, pinastric acid, xerocomic acid is described.
    常见的前体tetronic酸被用于合成几种硫化松香酸和pulvinic酸,这是在几种地衣和蘑菇中发现的颜料。该方法的关键特征是四甲基苄酯的两步烷基化和Suzuki-Miyaura交叉偶联。描述了几种天然产物的合成,如松果酸,松果酸,异黄酸。
  • Bioinspired Synthesis of Pulvinic Acids Including Xerocomic Acid and Fluorescence Properties of Bis‐lactone Intermediates

    日期:2023.2.17
    Six pulvinic acids (pulvinic, pinastric, atromentic, xerocomic, isoxerocomic, variegatic) and a polyporic acid (atromentin) were synthesised. A set of terphenyl-quinones was prepared through sequential Suzuki-Miyaura couplings. Then, a rearrangement into pulvinic bis-lactones was induced by the action of Ac2O/DMSO. Ring openings and deprotections achieved total syntheses. Fluorescence properties of
    合成了六种 pulvinic acids (pulvinic, pinastric, atromentic, xerocomic, isoxerocomic, variegatic) 和多孔酸 (atromentin)。通过连续的 Suzuki-Miyaura 偶联制备了一组三联苯醌。然后,通过 Ac 2 O/DMSO的作用诱导重排为 pulvinic 双内酯。开环和脱保护实现了全合成。确定了双内酯的荧光特性。
