  Novel anomeric spironucleosides and 1′‐cyano‐2′,3′‐didehydro‐2′,3′‐dideoxyuridine, a structural analogue of known anti‐HIV agents, were prepared by nucleophilic addition of organolithium reagents to 1′‐cyano‐2′‐deoxy‐ and 1′‐cyano‐2′‐deoxy‐2′β‐bromo‐uridine derivatives, respectively. The yield and distribution of products depended on the reaction conditions, which were studied in detail. Although none

• Kinetics and Stereoselectivity of Thiol Trapping of Deoxyuridin-1‘-yl in Biopolymers and Their Relationship to the Formation of Premutagenic α-Deoxynucleotides

  alpha-Deoxynucleotides are potentially deleterious lesions when produced in DNA. They are presumably formed in part via misrepair of the respective C1'-nucleotide radicals by thiols. However, the selectivity and extent to which these lesions are formed via this pathway has not been ascertained. Using the ability to independently generate deoxyuridin-1'-yl (4) at a defined site in a biopolymer, we have determined that thiol trapping in duplex DNA occurs with high stereoselectivity from the ct-face, resulting in restoration of the naturally occurring beta-deoxynucleotide. The observed stereoselectivity of thiol trapping in duplex DNA suggests that 4 is intrahelical. The rate constant for hydrogen atom donation to 4 is reduced 2-3-fold in double-stranded DNA compared to single-stranded DNA. This decrease is attributed to the relative inaccessibility of the C1'-position in duplex DNA. The combination of these two properties of 4 indicates that, at O-2 concentrations present in aerated water, alpha-deoxynucleotide formation should constitute a minor component of the reactivity of C1'-radicals. Accordingly, the chemical biology of other lesions derived from formal damage at C1'-position could be significant.
