title: A new entry to carbocyclic nucleosides: oxidative coupling reaction of cycloalkenylsilanes with a nucleobase mediated by hypervalent iodine reagent.
abstract: A novel method for synthesizing carbocyclic nucleosides was developed. The new synthesis includes a direct coupling reaction of cycloalkenylsilanes with a silylated nucleobase catalyzed by a hypervalent iodine reagent. By applying the method, a novel carbocyclic cytidine derivative having bis(hydroxymethyl)cyclohexene as a pseudosugar moiety, designed as a potential anti-HIV agent, was successfully synthesized.
