Short Abstract

Previous research discovered a novel type of products of G• dimerization, D1 and D2, formed as a result of one-electron oxidation of G derivatives. However, the mechanism of this dimerization remains elusive. It remains unclear which intermediate of G (G(N1-H) or G(N2-H)) participates in the formation of D1 and D2. By methylating the N1 nitrogen, it was demonstrated using HPLC and 1H-NMR analysis that hydrogens at the N2 position are absolutely required for D1 and D2 analogs to be produced.
