Ethyl salicylate condenses with different phenols in refluxing diphenyl ether to give various xanthones in good yields.In the case of resorcinol, hydroquinone, catechol and 3,4-xylenol corresponding phenyl salicylate derivatives are also obtained.Condensation with hydroxycoumarins affords pyranoxanthones, which can not be prepared by the Pechmann condensation of hydroxyxanthones.The structures of the intermediates and final products are established by spectral data (IR, PMR and 13C NMR).
