A new series of 3-cyano-2-pyridones derivatives have been prepared by reaction of enaminonitriles with pri-mary amine under solvent free condition. This procedure have the advantage of high yields and being environ-mentally-friendly

A novel methodology for the synthesis of substituted 2-aminopyridine δ-lactones is reported. It involves the reactions of enaminonitrile, 4,6,6-trimethyl-2-oxo-5,6-dihydro-2H-pyran-3-carbonitrile, with amines which is catalyzed by antimony trifluoride SbF3. The structures of the new compounds obtained were characterized by various spectroscopic methods (IR, 1 H NMR, 13 C NMR and MS).
