The condensation affordeddifferent corroles bearing core-heteroatoms at the predesignated locations. Regioselective α-α’ linkage be-tween pyrrole and furan or between pyrrole and pyrrole was achieved by keeping the linking carbon at differentposition of starting dipyrromethanes. The condensation was only fruitful when furan-containing dipyrromethaneswere condensed. IntroductionCorroles are porphyrinoid macrocycles bearing one bipyr-role ring junction and considered as 18π macro-aromaticsystems. The metal complexes of corroles and corrins areimportant biological cofactors and the study of their phys-ico-chemical properties has been contributed to the develop-ment of the chemistry of oligopyrrolic macrocyclic comp-ounds.Read More
