Acid catalyzed stereoselective rearrangement and dimerization of flavenes: synthesis of dependensin

Appropriately substituted flavenes undergo stereoselective rearrangement and dimerization when treated with methanolic hydrochloric acid to give benzopyranobenzopyrans. A rationale for the rearrangement is proposed. This synthetic methodology has been used for a high yield synthesis of the natural product dependensin.
