Synthesis of verdinochlorins: a new class of long-wavelength absorbing photosensitizers
摘要:
Reaction of 132-oxopyropheophorbide a with CH2N2 produced three isomeric methoxyverdinochlorins via expansion of the cyclopentanedione ring E; these long-wavelength absorbing verdinochlorins represent the first example of verdins with a reduced pyrrolic ring system, and their structural assignments have been made on the basis of 1H NMR studies; a mechanism of verdinochlorin formation is discussed.
