Abstract
Reaction of 2-methylimidazoles (II), 2-methylbenzimidazole (VI) and pyridine derivatives (VIII) with title γ-bromomethyl enone (I) provides access to the corresponding (benz)imidazolium and pyridinium salts, which cyclize under the action of base to give imidazolo[a]azepines (V), (VII) or indolizine derivatives (X), respectively.
