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 N3,5′-nucleosides by sodium periodate led to the corresponding N3,5′-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.
