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

A concise and highly efficient strategy for the synthesis of N-glycosyl imidazole analogues is reported. This reaction is based on a palladium catalysed decarboxylative allylation and three steps, namely, carbamation, decarboxylation and allylation are involved. All the substrates can afford the desired products with excellent yields and selectivities.

A novel 2′deoxyβDribofuranosyl pyrazineCnucleoside (6) was synthesized via a Stereospecific palladium(0)mediated crosscoupling reaction. The βconfiguration of this nucleoside was established by NOE analysis and the formation of a 5,5′anhydro nucleoside 5. The compound 4a, obtained via the crosscoupling reaction and selective deprotection, is a versatile intermediate for the preparation of other pyrazine
