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. Re- action 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.
