New syntheses of novel 1,2-pyrrolo[3,2-c]quinolines were established using 4-chloro-3-iodoquinoline as a synthon. The approach involved a palladium-catalyzed Sonogashira reaction of 4-chloro-3-iodoquinoline with appropriate arylacetylenes, followed by nucleophilic displacement of chlorine and cyclization. Studies on the reaction of 4-chloroquinoline derivatives with sodium azide led to the unexpected
