| Abstract: | Methyl pyropheophorbide-a (MPP-a) was used as starting material. The carbonyl group on E-ring of methyl pyropheophorbide-d was protected and the Grignard reaction with cycloheptyl magnesium bromide was performed. The sec-alcohol obtained from Grignard reaction was subjected to deprotection, dehydration, oxidation and other more reaction for converting hydroxyl group at 3-position into car- bon-carbon double bond and carbonyl group. The Grignard reaction of the carbon-oxygen double bond and following dehydration were carried out to form olefin. The synthesis of a series of new methyl pyropheo- phorbide-a substituted by cycloheptyl group at 3-position was completed. The structures of the compounds were characterized by elemental analysis, UV, IR and H NMR spectra. 1 |
