TL;DR: In this paper, β-formyl- and β,β′-diformylporphyrins were synthesized via 1,5-electrocyclization of porphyrinic azomethine ylides.
Abstract: Starting with β-formyl- and β,β′-diformylporphyrins, novel mono- and dipyrroloporphyrins were synthesised via 1,5-electrocyclization of porphyrinic azomethine ylides.
