摘要

Silica sulfuric acid is utilized as a green, highly efficient, heterogeneous and recyclable catalyst for the preparation of beta-enaminones and beta-enamino esters from amines and beta-dicarbonyl compounds under solvent-free conditions at 80 degrees C. Using this method, the title compounds are produced in high to excellent yields and in short reaction times.
