hexafluorophosphate (BOP) yielded the nucleoside C-2 tris(dimethylamino)phosphonium hexafluorophosphate salt as a stable, isolable species. This is in contrast to reactions of inosine nucleosides with BOP, where the in situ formed phosphonium salts undergo subsequent reaction to yield O6-(benzotriazol-1-yl)inosine derivatives. The phosphonium salt obtained from the 2'-deoxyxanthosine derivative can be effectively used
O6-苄基-3',5'-双-O-(叔丁基二甲基甲硅烷基)-2'-脱氧黄嘌呤与 1H-苯并三唑-1-基氧基-三(二甲氨基)鏻六氟磷酸盐 (BOP) 反应生成核苷 C- 2 三(二甲氨基)鏻六氟磷酸盐是一种稳定的可分离物质。这与肌苷核苷与 BOP 的反应形成对比,其中原位形成的鏻盐经历后续反应以产生 O6-(苯并三唑-1-基)肌苷衍生物。从2'-脱氧黄嘌呤衍生物得到的鏻盐可有效地用于合成N2-修饰的2'-脱氧鸟苷类似物。使用这种盐,还完成了丙烯醛-2'-脱氧鸟苷加合物的新合成。
