Spirolactones of xanthene. IV New method of xanthone synthesis by oxidation of novel spirolactones of dibenzo[c,h]xanthene and xanthenes.

open access: yesChemical and Pharmaceutical Bulletin, 1987
Dibenzo [c, h] xanthone and halogen-and methyl-substituted xanthones have been synthesized by the oxidation of novel spirolactones of dibenzo [c, h] xanthene and xanthene, which were prepared by a new condensation reaction of 1-naphthol or phenol derivatives with oxalic acid in the presence of sulfuric acid.
