Acyclic N 9 adenine nucleosides substituted at C-1′ position were prepared by the Mitsunobu reaction of 1-tert-butyldimethylsilyl-4-pivaloylbutan-1,2,4-triol (5) with adenine. Pivaloyl hydroxyl was modified to the phosphonomethoxy derivatives, and the tert-butyldimethylsilyl hydroxyl was converted to methoxy, azido, amino, fluoro, and α-hydroxyethyl and was eliminated to give vinyl. The resulting phosphonic
在 C-1' 位置取代的无环 N 9 腺嘌呤核苷通过 1-叔丁基二甲基甲硅烷基-4-新戊酰基丁烷-1,2,4-三醇 (5) 与腺嘌呤的光信反应制备。新戊酰基羟基被修饰为膦酰基甲氧基衍生物,叔丁基二甲基甲硅烷基羟基被转化为甲氧基、叠氮基、氨基、氟和α-羟乙基,并被消除得到乙烯基。所得膦酸也转化为前药。
