phenolic hydroxyl groups in 3 and 6 positions, depending on the experimental conditions (acetic
anhydride vs N-acetylimidazole), could be of interest for a temporary selective protection of one
of them. Both oxidative and non-oxidative cyclisation reactions involving the 2-prenyl group
could represent an alternative entry to the minor xanthones from G. mangostana with respect to
cumbersome and low-yielding extractive procedures, in view of detailed biological studies
requiring some amount of material.
