The effects of the reaction temperature, reaction time, solvent, catalyst and nitrogen source on the yield were investigated. The optimal conditions were as followed, the reaction temperature is 70℃, the molar ratio of aromatic aldehydes, acetacetic ester and ammonium bicarbonate is 0.5:1.0:0.5, the amount of catalyst is 10(mol)%. Under theseconditions, the highest yield of 1,4-dihydropyridine reached up to 93%. It was also observed that the catalyst could be recycled three times without obvious loss in catalytic activity. The procedure has the advantages of inexpensive catalyst, mild reaction condition, environmentally benign and simplicity. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
