Abstract
Derivatives of 2-methyl-3-benzoyl-5-hydroxynaphtho[1,2-b]furans and 3-acetonyl-4-benzoylhydroxynaphthols were synthesized by the reaction of tertiary enaminoketones withp-naphthoquinone. The transformations of derivatives of 2-methyl-3-benzoyl-5-hydroxynaphtho[1,2-b]furans into naphthofurandiones with nitric acid and transformation into the corresponding enamines with DMF acetal were investigated. It was shown that when the latter react withp-benzoquinone, derivatives of 2-(5-hydroxybenzofuryl-3)naphthofurans are formed.
