  Novel Synthesis and Anti-HIV Activity of 4′-Branched Exomethylene Carbocyclic Nucleosides Using a Ring-Closing Metathesis of Triene

  摘要：

  The exomethylene of 6 was successfully constructed from the aldehyde 5 using Eschenmoser's reagents. A triene compound 7 was cyclized successfully using Grubbs' II catalyst to give an exomethylene carbocycle nucleus for the target compound. A Mitsunobu reaction was successfully used to condense the natural bases (adenine, thymine, uracil, and cytosine). The synthesized cytosine analogue 20 showed moderate anti-HIV activity (EC50 = 10.67 M).
