The synthesis of orcinoylhydroquinones has been achieved by photochemical Fries rearrangement of their esters.A study of their oxidation (DDQ) shows that oxidative coupling occurs to produce a spirocyclohexenedione which can be thermally isomerised to the xanthone.The synthesis of a tetracyclic xanthone (related to bikaverin) is described.
