Abstract

2-Styrylpyridinium salts containing adamantane or aromatic fragments were prepared via a substitution reaction. It was found that quaternized substituted 2-ethenylpyridines undergo intramolecular cyclization under the action of bases, leading to trisubstituted cyclopropanes, as well as mono-, di-, and trisubstituted indolizines. A plausible mechanism was proposed for the formation of pyridylcyclopropanes.
