Abstract Synthesis of eight nucleoside analogues 4–11 with a methylenecyclobutane unit is described. Wittig reaction with 2‐hydroxymethylcyclobutanone 12 gave a mixture of Z (13) and E (14) derivatives, which was separated before functional modifications. The heterocyclic moieties were introduced via a Mitsunobu reaction either on the saturated chain or on the unsaturated chain. When adenine was used
摘要描述了具有亚甲基环丁烷单元的八种核苷类似物 4-11 的合成。Wittig 与 2-羟甲基环丁酮 12 反应得到 Z (13) 和 E (14) 衍生物的混合物,在功能修饰前将其分离。杂环部分通过饱和链或不饱和链上的 Mitsunobu 反应引入。当在该反应中使用腺嘌呤时,仅获得 N-9 取代产物。去除保护基团提供了目标产物。
