Acid catalyzed condensation of resorcinol or 2-methylresorcinol with 2 equiv. of an acetoxymethylpyrrole gave bis(pyrrolylmethyl)benzene derivatives in moderate yields; these afforded a series of novel aromatic benziporphyrins using the MacDonald “3 + 1” methodology.

23-Carba-oxybenziporphyrins, a new group of dicarbaporphyrinoids, are easily prepared by reacting tripyrrane analogues derived from resorcinol or 2-methylresorcinol with an indene dialdehyde under MacDonald '3+1' conditions. (c) 2006 Elsevier Ltd. All rights reserved.

Tripyrrane analogues were prepared by reacting resorcinol or 2-methylresorcinol with 2 equiv of an acetoxymethylpyrrole in the presence of p-toluenesulfonic acid and calcium chloride. Following removal of the benzyl ester protective groups, the resorcinol-derived benzitripyrrane was reacted with a pyrrole dialdehyde to give an aromatic hydroxyoxybenziporphyrin. However, furan and thiophene dialdehydes
