In order to expand study and application for the chlorophllous chlorins, pyropheophorbide-a methyl ester was used as a starting material. The chemical modifications and structural transformations along the terminals of N21-N23 axis were carried out to build active electron-accepting functional structures such as aldehyde, α-diketone, enenitrile and ketene moieties. The cyclizations with different electron-sufficient systems were accomplished to synthesize a series of unreported chlorins related to chlorophyll with multiple heterocyclic structures. The chemical structures of new compounds were characterized by elemental analysis, MS, UV-Vis, IR and 1H NMR spectra. Meanwhile the relevant formation process of the heterocyclic ring, the stereochemistry selectivity and the change of the electronic spectrum were discussed.

Key words: chlorophyll-a, chlorin, chemical modification, heterocyclization reaction, synthesis
