Abstract
A two-step synthesis of trifluoromethylated pyridones fused with different strained carbocyclic cores was developed. Acylation of the starting cyclic amino enones with ethyl malonyl chloride gave the corresponding amido enones that underwent the intramolecular Knoevenagel condensation to afford the target fused pyridones.
