1-(2-Bromophenyl)-1H-pyrrole and 1-(2,6-dibromophenyl)-1H-pyrrole react in the presence of catalytic amounts of rhodamine 6G (Rh-6G) and N,N-diisopropylethylamine (DIPEA) under blue light irradiation with aromatic alkynes and subsequently cyclize intramol

The endo-cyclic ring closure of 1-(2-(substituted ethynyl)phenyl)-1H- pyrroles 3-t and 1-(2-(substituted ethynyl)phenyl)-H-indole 4-o mediated by Lewis acid (I2) under mild conditions afforded substituted 5-iodopyrrolo[1,2-a]quinolines 5-t and 5-iodoindolo[1,2-a]quinolines 6-o in good to excellent yields. The reaction shows selective C - C bond formation on the more electrophilic alkynyl carbon, resulting in the regioselective 6-endo-dig-cyclized product. Iodo derivatives of pyrrolo- and indoloquinolines allow functional group diversification on the quinoline nucleus, which proves to be highly advantageous for structural and biological activity assessments.
