  • Patent number: 8394934
    Abstract: A method is disclosed for synthesizing 2?,3?-didehydro-2?,3?-dideoxynucleosides (d4Ns) from a nucleophile-mediated elimination, such as a telluride-mediated elimination reaction. After substitution of 2,2?-anhydronucleosides with a nucleophile, such as a telluride monoanion, a telluride intermediate is formed, and its elimination leads to formation of the olefin products (d4Ns). This disclosure describes this telluride-assisted (or nucleophile-assisted) reaction and how to facilitate the substitution and elimination in order to form d4Ns.
