Oxidative Coupling. Part 11. Approaches to the Synthesis of Bikaverin

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.
