Transformation of Natural Chlorophyll-a into Chlorophyll-c Analogs Possessing the 17-Acrylate Residue
Chlorophyll(Chl)-a derivatives possessing C18H-C17H-CH2-CH2 were transformed into Chl-c analogs possessing C18=C17-CH=CH through dehydrogenation to C18=C17, dihydroxylation to C18(OH)-C17(OH), and double dehydration. This is the first report on the synthesis of the latter porphyrin-acrylate conjugates by modifying natural chlorin propionate, Chl-a.
