Route for the Generation of Trifluoromethyl-Substituted Pyrrplo[3,2‑<i>c</i>]quinolines

Generation of trifluoromethyl-substituted pyrrolo­[3,2-<i>c</i>]­quinolines via a copper­(II)-catalyzed tandem reaction of <i>N</i>-(σ-iodoaryl)­alkynylimines with 2-isocyanoacetates is reported. The process involves a [3 + 2] cycloaddition and intramolecular C–C bond coupling, leading to the fluorine-containing <i>N</i>-heterocycles under mild conditions with high efficiency
