Abstract

A wide range of β-enamino esters have been synthesized in moderate to excellent yields by reacting 1,3-dicarbonyl compounds with amines in the presence of catalytic amounts of Yb(OTf)₃ (2 mol%). The reaction proceeds smoothly at ambient temperature under solvent-free conditions. The catalyst can be recovered and reused.
