title: Thiosugars. XII. Synthesis of new 3'-O-substituted 2',5'-anhydro-2'-thio-alpha-D-pentofuranosyl nucleoside analogues.
abstract: Methyl 2,5-anhydro-3-O-(2-methoxyethyl)-2-thio-beta-D-arabinofuranoside and methyl 2,5-anhydro-3-O-(2-fluorobenzyl)-2-thio-alpha-D-lyxofuranoside were transformed into the corresponding uridine, thymidine, cytidine and adenosine analogues, which exclusively exhibited the alpha-configuration irrespective of the anomeric configuration of the donor. The structure, configuration, and conformation of the products was elucidated by X-ray structure analyses. The nucleoside analogues were tested for antiviral activities.
