Abstract

The reaction of 1,4‐naphthoquinone (1) with 2,5‐dimethylpyrroles (7a‐7d) gives only 3‐(1,4‐naphtho‐quinonyl)‐2,5‐dimethylpyrroles. Extending the reaction to other quinones: 5‐hydroxy‐1,4‐naphthoquinone (2), 1,2‐naphthoquinone (3), quinoline‐5,8‐dione (4) and quinoxaline‐5,8‐dione (5), of which nothing was known, allows the synthesis of new pyrrolylquinones.
