The synthesis of porphyrins 12 with a pocket and an intramolecularly attached pyridine ring as a ligand is described.The key step involves porphyrin cyclization of 1,3,5-benzenetricarboxylic trisester (10), building up the pocket, and 3-pyridine (5), introducing the pyridine ligand, with four equivalents of pyrrole (11).Preparation procedures for the starting materials are described; NMR data of the target porphyrins 12 and their assignments are tabulated.
