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. Ringopenings and deprotections achieved total syntheses. Fluorescence properties of
