Abstract
- A DDQ-mediated tandem reaction of easily available o-hydroxy­aryl enaminones and cycloheptatriene is disclosed. It provides an effective and convenient method for the synthesis of 3-(cycloheptatrienyl)-substituted chromones in moderate to excellent yields with good functional group tolerance; this reaction involves an oxidative coupling and intramolecular annulation pathway.
