Substituted Pyridines

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 Brønsted 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–.Key words: ionic liquid, β-enaminones, β-enamino esters, 1,3-dicarbonyl compounds, amines, pyridines.
