摘要
A general and simple procedure was developed for the synthesis of beta-enaminones and beta-enamino esters by reacting 1,3-dicarbonyl compounds with amines in the presence of catalytic amounts of niobium pentachloride. The reaction proceeds smoothly at room temperature under solvent-free conditions and leads to chemo- and regioselective formation of enamine derivatives in high to excellent yields.
