A general and efficient palladium-catalyzed intramolecular cyclization reaction of beta-brominated porphyrins.
A general and efficient synthesis of fused five-membered porphyrins from the readily available beta-brominated porphyrins via palladium-catalyzed intramolecular cyclization has been developed, which can be applied for various metal complexes of beta-brominated porphyrins or free base ones and generally results in good yields of the fused five-membered porphyrins.
