The Mitsunobu reaction was applied to prepare, in one step, purine N 3,5′‐cyclonucleosides 10a–d. A subsequent ring opening in the ribose moiety of the resultant N 3,5′‐nucleosides by sodium periodate led to the corresponding N 3,5′‐cyclo‐2′,3′‐seconucleosides. These products consist of 5‐, 6‐, and 7‐membered tricyclic system which is the basic skeleton of TIBO derivatives, known antiviral agents.
应用光信反应一步制备嘌呤 N 3,5'-环核苷 10a-d。随后通过高碘酸钠在所得 N 3,5'-核苷的核糖部分开环导致相应的 N 3,5'-环-2',3'-第二核苷。这些产品由 5 元、6 元和 7 元三环系统组成,这是已知抗病毒剂 TIBO 衍生物的基本骨架。#本系列的前一篇论文:参考文献。1. †为了纪念和庆祝 Leroy B. Townsend 教授 70 岁生日。
