A versatile, alternative and environmentally benign three-component strategy to the synthesis of a series of 2-amino-chromenes has been successfully performed in water, using nanostructured diphosphate Na2CaP2O7 (DIPH) as a basic catalyst. The products are obtained in high recoveries from the one-pot multi-component reaction procedure involving carbonyl compounds, malononitrile and 1-naphtol, resulting
