A cross-coupling of unprotected ortho-bromoanilines with a wide range of cyclopropanols yields quinolines in a single operation via an intramolecular condensation and palladium-catalyzed oxidation sequence. Deuterium-labeling experiments provide direct evidence of a second equivalent of bromoaniline serving as the terminal oxidant.
