Acid Catalyzed

The acid catalyzed condensation of cyclohexenylacetic acid and its corresponding N-methylamide with formaldehyde was investigated. Good yields of the expected δ-lactone (V) or δ-lactam (IX) were obtained when trifluoroacetic acid was used both as catalyst and solvent for the reaction.
