Heterocyclic derivatives of naphthoquinones were synthesized via their 2‐bromo‐2,3‐dehydro‐intermediates. This new route may lead to the formation of benzo[ a ]phenothiazin‐5‐ones, benzo[ f ]quinoxalin‐6‐ones as well as their 1,4 (or 7,10) dihydroxy‐derivatives in high yields. The possible mechanisms involved in the formation of these compounds are discussed.
