Abstract

It was shown that ketonimines, which can have imine--enamine tautomerism, react with pyrylium salts in the enamined form. In such reactions, the 2-benzopyrylium salts are transformed into unsaturated ketones, and their monocyclic analogs are transformed into either quinolizinium salts or pyridinium salts depending on the structure of the initial imine.
