A facile enamination of 1,3-dicarbonyl compounds with amines has been developed that affords good to excellent yields of β-enamino esters and β-enaminones using Bronsted acidic ionic liquid 1-methylimidazolium trifluoroacetate ([Hmim]+Tfa-) at room temperature. This methodology has been extended for the synthesis of substituted pyridines in excellent yield by a one-pot, three-component reaction of 1,3-dicarbonyl compounds, ammonium acetate, and alkynone in the presence of [Hmim] +Tfa-.

β-Enaminones have been synthesized in very good yield under solvent-free conditions from differently substituted amines and β-diketones in the presence of Yb(OTf)3 as catalyst. The method is applicable to cyclic and acyclic ketones, aromatic an
