Abstract
The action of sulfuric and polyphosphoric acids and sodium hydroxide on 3-carbethoxy-4,5-dioxonaphthofuran derivatives was studied. 2-Methyl- and 2-phenyl-3-carboxy-4,5-dioxonaphthofurans were obtained by the action of sulfuric acid on the indicated compounds. The action of alkali on 2-methyl- and 2-phenyl-3-carbethoxy-4,5-dioxonaphthofurans and 2-phenyl-4,9-dioxonaphthofurans leads to the formation of 2-hydroxy-3-acetonyl- and 2-hydroxy-3-phenacyl-1,4-dioxonaphthalenes.
