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.

Synthesis of new xanthene derivatives
Xanthene dyes, including fluorescein, are a well-known class of fluorescent dyes, which have widespread applications in natural sciences. The synthesis of xanthene derivatives via acid catalyzed condensation of substituted phenols with phthalic anhydride, to afford the asymmetric derivatives, is well established.
