We have developed an efficient route for the synthesis of a novel bicyclic nucleoside using a key intermediate 13, which was prepared from 1,2:5,6-di-O-isopropylidene-α-d-glucose. 1,2-Nucleophilic addition of aldehyde 8 with allyltrimethylsilane and intramolecular Williamson reaction were successfully achieved to synthesize an intermediate with a 3,7-anhydrooctofuranosyl skeleton.
我们开发了一种使用由 1,2:5,6-二-O-异亚丙基-α-d-葡萄糖制备的关键中间体 13 合成新型双环核苷的有效途径。成功地实现了醛8与烯丙基三甲基硅烷的1,2-亲核加成和分子内Williamson反应,合成了具有3,7-脱水八呋喃糖基骨架的中间体。
