Methyl pyropheophorbide-d was used as starting material and the Knoevenagel reaction of the aldehyde group on pyropheophorbide with active methylene group in β-diketone, α-cyanoketone or malono- nitrile was carried out to complete the synthesis of derivatives of methyl pyropheophorbide-a substituted with five-membered heterocycle at 3-positipon. The structures of all these new compounds were characterized by elemental analysis, UV, IR and 1H NMR spectra.

Key words: Knoevenagel reaction, photodynamic therapy, pyropheophorbide
