Abstract: The cyclization of 3-(substituted anilino-methylene)-6-methyl-α,γ-Pyronone was carried out in the presence of hydrochloric acid. Seven N-substituted phenyl-6-methyl-4-oxo-dihydro-pyridine-3-carboxylic acids were synthesized by cyclization with their structures being identified by elemental and NMR analyses.

Key words: cyclization, pyronone, oxo-pyridine carboxylic acid, synthesis
