The anion of $6-benzenesulfonyl-3-O-benzyl-6-deoxy-1,2-O-isopropylidene-{\alpha}-d-glucofuranose$ was stable and reacted with carbon electrophiles to give higher-carbon sugars. Reactions of uridine 5'-aldehyde with phosphoranes afforded heptofuranose nucleosides.

1-[Ethyl (E)-5,6-dideoxy-2,3-O-isopropylidene-$\beta$-D-ribo-hept-5-enofuranosyluronate] uracil(12) was synthesized. Other various heptofuranose uncleosides were also synthesized from uridine and adenosine by two-carbon chain extension using Witting reaction.
