Synthesis and Antiviral Activities of 1,2,3-triazole Functionalized Thymidines: 1,3-dipolar Cycloaddition for Efficient Regioselective Diversity Generation
Efficient regioselective synthesis of nucleoside conjugates was achieved by cycloaddition reaction of azides and alkynes using sodium ascorbate/CuSO4 system as a catalyst. These 16 novel thymidine analogues were obtained in excellent yields (75–100%), employing mild reaction conditions with a broad scope of structural modification. For the compounds tested, no specific antiviral effects could be witnessed against a broad range of viruses.
