Abstract
Reaction of 13(2)-oxopyropheophorbide a with CH2N2 produced three isom eric methoxyverdinochlorins via expansion of the cyclopentanedione rin g E; these long-wavelength absorbing verdinochlorins represent the fir st example of verdins with a reduced pyrrolic ring system, and their s tructural assignments have been made on the basis of H-1 NMR studies; a mechanism of verdinochlorin formation is discussed.
