Abstract: Many therapeutically important nucleoside analogues can be synthesized from versatile
azidonucleoside intermediates. We have synthesized 3’-xylo-azidonucleoside analogues of thymidine
and 2’-deoxyadenosine via Mitsunobu-DPPA and triflate-lithium azide strategies. On comparing the
two azidation strategies on nucleoside analogues, we found that Mitsunobu-DPPA azidation is better
than triflate-lithium azide azidation in terms of yield and reaction conditions.
