A novel, efficient and straightforward method to synthesize 1,4-dihydropyridine compounds with excellent yields is reported through Hantzsch reaction of aldehydes, ammonium acetate and ethyl acetoacetate or methyl acetoacetate using humic acid as the catalyst. This method has high yield and less pollution. The catalyst is easy to recycle and environment friendly.

Key words: humic acid, catalysis, 1,4-dihydropyridine
