title: Synthesis of chlorophyll-f analogs possessing the 2-formyl group by modifying chlorophyll-a.
abstract: A methyl group at the 2-position of methyl mesopyropheophorbide-a was transformed to the 2-formyl group to give methyl mesopyropheophorbide-f, one of the chlorophyll-f analogs. The 2-formylation moved the redmost electronic absorption band in a solution to a longer wavelength and the bathochromic shift was comparable to that by the 3-formylation. Zinc complex of the synthetic compound in solutions showed similar visible absorption spectra as those of naturally occurring chlorophyll-f.
