| Abstract: | An efficient one-pot synthesis of 2-amino-5,10-dihydro-5,10-dioxo-4-phenyl-4H-benzo[g]chromene derivatives has been achieved by the reaction of 2-hydroxynaphthalene-1,4-dione, cyanothioacetamide, and aromaticaldehyde in EtOH at room temperature catalyzed by ZnCl2. The structures of the products were characterized by infrared, 1H NMR, mass, and elemental analysis.  Additional information ACKNOWLEDGMENT We thank the University Grants Commission, New Delhi (F.
