Treatment of 3-acyl-2-[(2,2-dimethyl-6-oxo-1,3-dioxin-4-yl)methyl]-5-methoxy-1,4-naphthoquino nes with K2CO3 in an alcohol brought about the intramolecular condensation to give 1-alkyl-3-hydroxy-8-methoxy-9,10-anthraquinone-2-carboxy-lates in good yields, while the same naphthoquinone gave 1-hydroxy-8-methoxy-9,10-anthraquinone-3-acetic acid in good yield by treatment with KHMDS.
