PHOTOREACTIONS OF QUININE IN AQUEOUS CITRIC ACID SOLUTION. PART 2. SOME END-PRODUCTS
A novel spiro-compound derived from 2',4'-bis-(1,3-dicarboxy-2-hydroxyprop-2-yl)-1',4'-dihydroquinine has been identified as a major end-product of the irradiation of quinine in aqueous citric acid solution. 7'-(1,3-Dicarboxy-2-hydroxyprop-2-yl)deoxyquinine and products arising from the cleavage of quinine at C-9 were also detected in the reaction mixture.
