Abstractmagnified image The usefulness of 3‐iodoindole available for introduction of an indole unit is presented. The reaction of 3‐iodoindole with 2‐bromo(or methyl)‐1,4‐naphthoquinone in acetic acid gave 2‐bromo(or methyl)‐3‐(3‐indolyl)‐1,4‐naphthoquinone. On the other hand, the reaction of 3‐iodoindole with 2‐bromo‐1,4‐naphthoquinone in the presence of cesium carbonate in acetonitrile produced 2‐(1‐indolyl‐3‐iodo)‐1,4‐naphthoquinone. J. Heterocyclic Chem., (2010).
