The acyclic azanucleosides with 2-, 3-, or 4-aminobenzenesulfonyl function at the nitrogen atom of the sugar mimic were prepared by coupling of 2-, 3-, or 4-nitro-N-(2-pivaloyloxyethyl)-N-(pivaloyloxymethyl)benzenesulfonamide with the silylated pyrimidine nucleobases followed by the reduction of the nitro group with sodium dithionite in aqueous solution or the palladium-catalysed transfer hydrogenation
通过偶联2-、3-或4-硝基-N-(2-新戊酰氧基乙基)-N-(新戊酰氧基甲基)苯磺酰胺与甲硅烷基化的嘧啶核碱基,然后在水溶液中用连二亚硫酸钠还原硝基或钯催化的转移氢化。在体外评估了氮杂核苷对几种 RNA 和 DNA 病毒的活性,但发现没有活性。
