Reductive N Alkylation of Cyclo[8]pyrroles

摘要

Cyclo[8]pyrrole (1),although lacking bridging meso carbon atoms,may be considered as a larger analogue of porphyrin (2) in that it is flat and aromatic (see Scheme I).For this reason,we have been interested in exploring the chemical behavior of cyclo[8]pyrrole and contrasting it to that of the porphyrins.
