experimental part, p. 772 - 779 (2012/06/16)
Triazolo-fused 3′,5′-cyclic nucleoside analogues were synthesized by an intramolecular 1,3-dipolar cycloaddition of nucleoside-derived azido-alkynes in a regio- and stereospecific manner. The thymine nucleoside base in these target compounds was transform
Synthesis and biological activity of 3'-azido- and 3'-amino substituted nucleoside analogs

The product distribution obtained in the reaction of 1-(5-0-trityl-0-mesyl-2-deoxy-β-D-erythro-pentofuranosyl)-2,4-(1H, 3H)-pyrimidinedione with lithium azide in N, N'-dimethylformamide at 100°C depends on the nature of the substituent in 5. The results may be explained by a difference in the acidity of the pyrimidinedione. The reaction of the more acidic nucleosides (X = I, F) appears to proceed preferentially through the 2,3'-anhydro intermediate, whereas for the less acidic products (X = H, CH3) direct nucleophilic displacement by the azide ion predominates. The different 3'-azidfo derivatives were reduced to 3'-amino compounds. All 3'-azido- and 3'-aminopyrimidine nucleosides were tested against herpes simplex virus, vaccinia and vesicular stomatitis virus and on murine L1210 cell growth. None of the substances exhibited significant activity.
One-Step Synthesis of 5'-Azido-nucleosides
Yamamoto, Isamu,Sekine, Mitsuo,Hata, Tsujiaki
, p. 306 - 310 (2007/10/02)
Regioselective azidation of unprotected or appropriately protected nucleosides was conducted by means of the reagent triphenylphosphine-carbon tetrabromide-lithium azide.By use of this reagent, 5'-azido-5'-deoxynucleosides were prepared conveniently in one step from nucleosides in high yields.Secondary hydroxy-groups of appropriately 5'-protected nucleosides were also converted by the reagent to azido-functions with complete inversion.
