A variety of β-enaminoketones and esters have been synthesized in high to exellent yields by reacting β-dicarbonyl compounds with amines in the presence of a catalytic amount of indiumtribromide. The reaction proceeds smoothly at room temperature in a short reaction time under solvent-free conditions.

An efficient method for the enamination of 1,3-dicarbonylcompounds by employing ceric ammonium nitrate (CAN) as the catalyst has been described. A variety of β-amino-α,β-unsaturated ketones and esters have been synthesized in excellent yield within a short reaction time under solvent-free conditions.
