    • Substituted propargylethoxyamido nucleosides are disclosed having structure (I) wherein X is selected from the group consisting of amino alkanoic acid, alkylamino benzoic acid, α-amino acid, and 4-amino-2-butynoic acid. R1 and R2 taken separately are selected from the group consisting of -H, lower alkyl, protecting group, and label; R3 is selected from the group consisting of -H and lower alkyl. B is a 7-deazapurine, purine, or pyrimidine nucleoside base. When B is purine or 7-deazapurine, the sugar moiety is attached at the N9-position of the purine or deazapurine, and when B is pyrimidine, the sugar moiety is attached at the N1-position of the pyrimidine. When B is a purine, the adjacent triple-bonded carbon is attached to the 8-position of the purine, when B is 7-deazapurine, the adjacent triple-bonded carbon is attached to the 7-position of the 7-deazapurine, and when B is pyrimidine, the adjacent triple-bonded carbon is attached to the 5-position of the pyrimidine. W¿1? is selected from the group consisting of -H and -OH. W2 is -OH or a moiety which renders the nucleoside incapable of forming a phosphodiester bond at the 3'-position. W3 is selected from the group consisting of -PO4, -P2O7, -P3O10, phosphate analog, and -OH. Additionally, a primer extension method is provided employing the above X-substituted propargylethoxyamido nucleosides, and polynucleotides including the above X-substituted propargylethoxyamido nucleosides is provided.
