This paper deals with the synthesis of the novel 2',3'-dihalo-2',3'-dideoxy- and 2',3'-didehydro-2',3'-dideoxy-analogues of 6-azacytidine as potential antiviral substances. The compounds were prepared by means of the appropriate reagents – triphenylphosphonium halogen salts. The first step of the 6-azacytidine conversion results in 2,3-epoxynucleosides as against deoxygenation of uridine and thymidine, when O2, 2'-cyclonucleosides are generated.References
