Silica supported sodium hydrogen sulfate (NaHSO4•SiO2) has been found to be an efficient heterogeneous catalyst for the condensation of 1,3-dicarbonyl compounds with primary amines to give the corresponding β-enamino ketones and esters in good yields at room temperature. The catalyst could be easily recovered from the reaction mixture.

Key words: β-enamino ketone and ester, catalysis, NaHSO4•, SiO2, 1,3-dicarbonyl compound
