Abstract

An efficient method for the synthesis of β-enaminones and β-enaminoesters using a combination of [(PPh3)AuCl]/AgOTf as catalyst has been developed. The reaction between 1,3-dicarbonyl compounds and primary amines was carried out under solvent-free conditions with low catalyst loading in good to excellent yields at room temperature.
