Synthesis of a series of aromatic benziporphyrins and heteroanalogues via tripyrrane-like intermediates derived from resorcinol and 2-methylresorcinol

Article abstract of DOI:10.1021/jo201098c

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
