Chlorophyllous degraded products are ideal synthetic precursors for the synthesis of photodynamic therapy drugs. To obtain chlorophyllous photosensitizer, methyl pyropheophorbide-d was used as starting material, and its formyl and carbonyl groups on E-ring were modified by allomerization, Knoevenagel reaction, Hener reaction, Tiffeneau-Demjano rearrangement, Friedlaender condensation and reduction to build different chemical structures at 3-position and exocyclic E-ring. A series of chlorins with basic skeleton of chlorophyll were synthesized, and the relations between the molecular structures and their UV-Vis spectra were discussed. The possible mechanisms about corresponding reactions were tentatively proposed. The structures of new-reported chlorophyll derivatives were characterized by UV, IR, 1H NMR and elemental analysis.
