The b-keto ester undergoes condensation reactions with aliphatic and aromatic amines in ethanol to give high-yielding b-enamino ester. The method is simple, cost-effective and environmentally benign. Structural characterization of the synthesized compounds was carried out by spectroscopic methods (1H NMR, 13C NMR and DEPT).
