An unusual oxidative cyclization of chalcones by thallium (III) trinitrate (TTN) to 4-methoxyaurones has been studied. A key feature of this reaction is the introduction of a methoxyl group into the aurone skeleton. Several reactions have been performed to understand the mechanism and regiochemistry of cyclization.
