Krueger, Oliver published the artcileOxidative Cleavage of a Cyclobutane Pyrimidine Dimer by Photochemically Generated Nitrate Radicals (NO3•), Recommanded Product: 3-Methylpyrimidine-2,4(1H,3H)-dione, the publication is Organic Letters (2001), 3(10), 1455-1458, database is CAplus and MEDLINE.
Photochem. generated nitrate radicals (NO3•) cleave the stereoisomeric N,N-dimethyl-substituted uracil cyclobutane dimers into the monomeric uracil derivative as the major reaction pathway. The reactants thus studied were cis–syn-1,3-dimethyluracil dimer [i.e., (4aR,4bS,8aS,8bR)-rel-hexahydro-1,3,6,8-tetramethylcyclobuta[1,2-d:4,3-d‘]dipyrimidine-2,4,5,7(3H,6H)-tetrone], trans–syn-1,3-dimethyluracil dimer, cis–anti-1,3-dimethyluracil dimer, and trans-anti-1,3-dimethyluracil dimer. A preferred splitting of the syn dimers was observed The reaction is expected to proceed through initial one-electron oxidation with formation of an intermediate cyclobutane radical cation. In addition to cycloreversion, competing reaction steps of a cation radical intermediate, which lead to the observed byproducts, are suggested.
