2-Amino-3-iodopyridine

2-Amino-3-iodopyridine (3-Iodopyridin-2-amine) can couple with formyl derivatives under copper-catalyzed indole synthesis conditions, followed by constructing azidoindole analogs through copper-mediated conjugate addition. Its nucleophilicity is lower than the corresponding anilines used in indole synthesis, which may pose a potential obstacle for future synthesis.
