A nonconventional approach to the preparation of morphinans has been applied to the total synthesis of thebainone-A and β-thebainone-A. Noteworthy features of this synthesis are the regiospecificity of the Diels-Alder reaction to form 9 and of the enolization-hydroxylation of 11, the unusual aromatization of 14 as well as the selectivity of the intramolecular Michael addition of the of the anine to
