Photoinduced Cross Coupling Reaction of Covalently Linked Tyrosine-Pyropheophorbide a and Tyrosine-9-Desoxomesopyropheophorbide a to 1,4-Benzoquinone

Article abstract of DOI:10.1246/cl.1999.833

Irradiation of tyrosine-linked pyropheophorbide a and 1,4-benzoquinone (BQ) in benzene led to a clean formation of a quinone-linked product, while photoreaction of 9-desoxomesopyropheophorbide a and BQ produced a quinone-linked 9-desoxomesopyropheophorbide a and a quinone-inked 9-desoxophylloerythrin a.
