The Chemistry of Pyrrolic Compounds. LXIII Synthetic Studies of Petroporphyrins with Fused Six-Membered Ring Systems

Clezy, Peter S.,Prashar, Jognandan K.

, p. 825 - 837 (2007/10/02)

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).
