In the presence of methanesulfonic acid as catalyst, the condensation reactions of 5,5鈥?dialkyldipyrromethanes with p-hydroxyacetophenone in methanol resulted in a mixture of the unexpected polysubstituted 15伪,20伪-di(4-hydroxylphenyl)calix[4]pyrroles and the expected 10伪,20尾-di(4-hydroxylphenyl)calix[4]pyrroles in comparable lower yields. The crystal structures of the new calix[4]pyrroles and their oxyacetate derivatives were successfully determined by X-ray diffraction and the intermolecular interactions in the solid state is briefly discussed.
