In last years a number of 1,2,3-triazolylnucleoside derivatives have been synthesized and investigated, leading to discovery of substances with antiviral and anticancer activity, enzyme inhibitors, adenosine receptor agonists and antagonists. Our group has reported the synthesis of 2,6-bistriazolyl purine arabino- and ribonucleosides in Cu(I)-promoted azide-alkyne cycloaddition reactions. The reactivity of products towards nucleophilic species has also been discussed. In addition to our previous work, herein we report the synthesis of the novel bistriazolylpurine deoxyribonucleosides and their reactions with N- and S-nucleophiles.
