Hexofuranosyl nucleosides are considered as conformationally restricted acyclic nucleosides using a furanose ring to link the diol backbone to the nucleobase. The phosphoramidite of 1-(2,3-dideoxy-beta-D-erythro-hexofuranosyl)thymine was synthesized from thymidine with formation of a new stereocentre at C-5' and the nucleoside

3-(2-Deoxy-beta-D-erythro-pentofuranosyl)-6-hydroxy-5,6,7,8-tetrahydropyrimido[1,2-a]purin-10(3H)-one is formed in low yield by the reaction of acrolein with 2'-deoxyguanosine. The nucleoside and an oligodeoxynucleotide containing it have been synthesized. For preparation of the nucleoside 2'-deoxyguanosine was alkylated at the N1 position using 1-bromo-3-butene to give 1-(3-butenyl)-2'-deoxyguanosine.

The synthesis of oligonucleotides containing 2'-deoxy-2'-fluoro-4'-thioarabinonucleotides is described. 2'-Deoxy-2'-fluoro-5-methyl-4'-thioarabinouridine (4'S-FMAU) was incorporated into 18-mer antisense oligonucleotides (AONs). 4'S-FMAU adopts a predominantly northern sugar conformation. Oligonucleotides containing 4'S-FMAU, unlike those containing FMAU, were unable to elicit E. coli or human RNase
