The synthesis of 1-[1-(4-hydroxybutyl)-1,2,3-triazol-(4 and 5)-ylmethyl]-1H-pyrazolo[3,4-d]pyrimidines 11a,b, 12a,b and 13-17 as carboacyclic nucleosides is described. The compounds 8a,b were condensed, separately, with compound 7 via 1,3-dipolar cycloaddition reaction to afford, after separation and deprotection. 1,4-regioisomers 11a,b and 1,5-regioisomers 12a,b. The deprotected carboacyclic nucleosides
