One-pot synthesis of 14-aryl-14H-7-oxa-benzo[a]naphthacene-8,13-diones was developed by the reaction of 2-hydroxynaphthalene-1,4-dione, aromatic aldehydes, and 2-naphthol in the presence of acetic acid. The structures of these compounds were identified by elemental analyses, infrared, 1H NMR, and mass.
