A [3C + 3C] annelation using 1,1-bis(ethylthio)-2-propanone was applied to a new synthesis of the aporphine alkaloids. Condensation of the ketone with the Mannich base gave two isomeric cyclohexenones, which were converted into the aporphine framework by aromatization. (±)-Glaucine and (±)-nantenine were prepared by employing this new aromatic synthesis.
