Molecular structure of a unique photoproduct of plastoquinone-1 [2,3-dimethyl-5-(3-methylbut-2-enyl)-1,4-benzoquinone]
Abstract
Near-u.v. irradiation of plastoquinone-1, a model for the electron transport quinones in plants, gives rise to the unique dimer, 5,6,6a,7,7a,11b-hexahydro-2,3,5,7,7,9,10-octamethyl-6, 11a, 11c-metheno-1H-benzo[c]fluorene-1,4,8,11(4aH)-tetrone.
