A series of 2-amino-3-cyano-4-aryl-4H,5H-pyrano[3,2-c]pyran-5-one was synthesized by a three-component reaction of aromatic aldehydes, malononitrile and 4-hydroxy-6-methylpyran-2-one using triethylbenzylammonium chloride as catalyst in aqueous media. This method has some advantages of good yields, less pollution, simple operation and environmental friendliness.

Key words: pyrano[3,2-c]pyran-5-one, three-component, aqueous media, one-pot synthesis
