  Oxidation of Acetylated Guanosine by 3,3-Disubstituted 1,2-Dioxetanes through Nucleophilic Attack on the Peroxide Bond: Model Studies on the Oxidative DNA Damage by Reactive Peroxides

  摘要：

  The reaction of the disubstituted 3-(methoxymethyl)-3-phenyl-1,2-dioxetane (1a) with the acetylated guanine nucleoside (2) in methanol affords 8-methoxyguanosine 5 as oxidation product, as well as guanine (6) and 1-methoxyribose 7 by deglycosylation (total yield ca. 30%). The dioxetane-derived reduction product constitutes the 1,2-diol 40, while the major dioxetane-derived product (85%) is omega-methoxyacetophenone (3a). A Grob-type fragmentation is made responsible for the exclusive formation of the dioxetane cleavage products in the reactions with the acetylated nucleosides 8-10 derived from adenine, cytosine, and thymine. Rather than redox chemistry, this guanosine oxidation, unprecedented for peroxides, is proposed to involve nucleophilic attack by the N-7 atom of the nucleosides on the peroxide bond of the dioxetane la electrophile to generate a zwitterionic intermediate. S(N)2 attack by methanol at the C-8 position of the guanine moiety in the zwitterionic intermediate leads to the 8-methoxyguanosine 5 and the diol 4a. Alternatively, heterolytic cleavage of the glycosidic bond affords the methoxylated ribose 7 (after methanol trapping) and the N-7-alkoxylated guanine. The latter, after protonation, subsequently undergoes Grob fragmentation into guanine (6) and the dioxetane decomposition products omega-methoxyacetophenone (3a) and formaldehyde. We propose that the present novel oxidation of guanosine is general for electrophilic peroxides and may constitute a prominent route of oxidative DNA damage. In contrast, the corresponding 3-(bromethyl)-3-phenyl- 1,2-dioxetane (1b) gave with the guanosine 2 an intractable, complex product mixture, for which presumably the bromo substituent is responsible on account of competitive alkylation chemistry. However, with the 2'-deoxythymidine 10, a novel acid-catalyzed ring-opening of the bromo-substituted dioxetane Ib to its beta-methoxy hydroperoxide 11b is observed, a reaction which does not take place for the methoxy-substituted dioxetane 1a. This unusual process for simple dioxetanes is rationalized in terms of stabilization of the intermediary benzylic cation by the adjacent beta-bromo substituent through neighboring group participation.
