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。
