series of 3′-β-C-branched anhydromannitol nucleosides were conveniently synthesized starting from commercially available d-ribose. The reaction sequences were: (i) conversion of the protected pentofuranose to the corresponding nitrohexopyranose; (ii) addition of the conjugated base of the nitrosugar to formaldehyde; (iii) removal of the nitro group by n-tributyltin hydride treatment and (iv) Mitsunobu

The 3'-beta-C-branched anhydrohexitol nucleosides have been conveniently synthesised starting from commercially available D-ribose following the reaction sequence: (i) conversion of protected pentofuranose sugar to the corresponding hexopyranosyl nitrosugar (ii) addition of the conjugate base of nitrosugar to formaldehyde to obtain C-branched nitro sugar (iii) removal of nitro group by n-tributyltin hydride treatment and (iv) Mitsunobu type alkylation to build up the nucleobase.
