NaHSO4•SiO2作催化剂, 1,3-二羰基化合物和伯胺在室温下反应合成了一系列β-烯胺酮(酯), 该法反应条件温和, 产率高, 催化剂能回收再利用.

关键词: 1,3-二羰基化合物, 催化, β-烯胺酮(酯), SiO2, NaHSO4•

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
