Intramolecular cyclization of propargylammonium halide derivatives was carried out giving methylated heterocyclic aromatic compounds with fused thiazole and imidazole nuclei. Some of these reactions were accompanied by rearrangement which might be caused by ring opening of the quaternary heterocyclic compounds.
