2′-deoxynucleosides to furanoidglycals have been discovered. These phosphorimides, (Ph2PS)2NH and (Ph2PSe)2NH, were shown to effectively mediate persilylation of 2′-deoxynucleosides allowing the elimination of the nucleobase giving the corresponding glycal. These mild conditions were demonstrated in the syntheses of glycals with various substitution patterns while minimizing the formation of undesired byproducts

1,2-Dideoxyribose 5-O-succinate, a component of solid support employed in the synthesis of ribozymes, was synthesized from thymidine. The key step was elimination of nucleobase from 2 to afford glycal 3. A number of catalysts for this reaction were tested, resulting in improved and scaleable synthesis. Hydrogenation of the resulting glycal afforded 1,2-dideoxyribose derivative 4 in a high yield.
