2-pyridone nucleus by ferric chloride promoted [3+3] cycloaddition in propionic acid. The tandem process involves cyclization of Michael adduct followed by aromatization. Thus, different substituted 1,2-dihydro-2-oxo-3-pyridinecarboxylate and 1,2-dihydro-2-oxo-3-pyridinecarboxamide derivatives were prepared in good yields from various enones with malonamic ester and malonamide, respectively
