The allomerization of methyl pyropheophorbide-a, used as starting material, was carried out under the alkaline condition to separate a series of oxidized and rearranged products at exocyclic E-ring and C-12-methyl group. The same reaction of chlorinated methyl pyropheophorbide-a also came through similar processes. The further oxidations of C-132-and C-12-oxidized products gave two different results, the former reacted quickly and produced complicated compounds, the latter HH basically HH unchanged under the same condition. The structures of all new chlorin derivatives were characterized by elemental analysis, UV, IR and 1H NMR spectra. The possible mechanisms about corresponding reactions were tentatively proposed.
