Abstract

Concise Approach to 1,4-Dioxygenated Xanthones via Novel Application of the Moore Rearrangement. -A general route is developed for xanthones (V), which are otherwise difficult to obtain, via Moore rearrangement (II) → (III). Further investigations, i.e. methylation of hydroxyl substituents, reveal that the reported structure (VIIIa) for dulcisxanthone C has to revised to (VIIIb). -(NICHOLS, A. L.; ZHANG, P.; MARTIN*, S.
