<P>Methyl pyropheophorbide-c? was used as starting material and the Knoevenagel reaction of the aldehyde group on pyropheophorbide with active methylene group in /?-diketone, a-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 LH NMR spectra.</P>
