Methyl 132-oxopyropheophorbide-a was prepared using one pot method from chlorophyll-a, and subsequently reacted with o-diaminobenzene to produce four chlorins fused with nitrogenous heterocycle derivatives. The hyperactive functional groups such as formyl and formymethyl groups were introduced at 3-position by oxidation with thallium nitrate or osmium tetroxide. Friedländer condensation of C3-formymethyl group with o-aminobenzaldehyde was carried out smoothly to build quinolinic structure. The five-membered heterocyclic rings were established at 3-position via the 1,3-dipolar cycloaddition reaction of C3-vinyl group with diazomethane and benzonitrile oxide. The structures of new chlorins with chlorophyllous basic skeleton were characterized by UV, IR, 1H NMR and elemental analysis.
