The synthesis of 2-amino-2-chromenes catalyzed by tetrasodium ethylenediaminetetraacetate (EDTA-4Na) via a one-pot three-component reaction of aromatic aldehyde, malononitrile and 1-naphthol in volume fraction of 95% ethanol has been described. This method offers several advantages such as low cost of the catalyst, mild conditions, good yield, simple experimental and work-up procedure, and reusability of cata-lyst.
