【Abstract】 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 catalyst.更多还原
