2-(2-Hydroxynaphthalene-1-yl)pyrrolidine-1-carboxamides undergo ring opening in the presence of trifluoroacetic acid and 2-naphthol leading to the formation of new substituted dibenzoxanthenes. Reaction of 2-(2-hydroxynaphthalene-1-yl)pyrrolidine-1-carboxamides with polyatomic phenols at the same conditions was found leading to diarylmethane derivatives and calix[4]resorcinols with naphthyl fragment acting as a leaving group.

Reaction of 2-methylresorcinol and pyrogallol with urea acetals of various structures was studied. Depending on the structure of the acetal used, reaction was established to result in eiter calix[4]resorcinols containing urea fragment or in imidazolidin-2
