A new and efficient synthesis of 2-amino-4H-chromene derivativeswhich have remarkable pharmacological properties is developed by one-pot three-component efficient reaction between aldehydes, malononitrile, and α or β-naphthol in MeOH as solvent using DABCO-CuCl complex as an effective catalyst at room temperature. The structures of synthesized compounds were characterized by techniques of IR,1H-NMR, Mass and elemental analysis. This method provides an efficient improved pathway for the synthesis of chromenes in the terms of excellent yields, short reaction times and reusability catalyst.
