Several approaches to the synthesis of porphyrins bearing fused six-membered ring systems were explored with the aim of obtaining the petroporphyrin (4a).This was ultimately achieved by an intramolecular cyclization of a porphyrin with a propanoyl chloride side chain in the presence of stannic chloride.Methylation of the intermediate ketone with CH3Li and reduction of the resultant alcohol with NaBH3CN/ZnI furnished (4a).
