The syntheses and the fluorescence properties of 7H-3,6-dihydro-1,2,3-triazolo[4,5-d]pyrimidin-7-one 2′-deoxy-β-D-ribonucleosides (=2′-deoxy-8-azainosine) 3 (N3), 15 (N2), and 16 (N1) as well as of 1,2,3-benzotriazole 2′-O-methyl-β- or -α-D-ribofuranosides 6 (N1) and 24 (N1) are described. Also the fluorescence properties of 1,2,3-benzotriazole 2′-deoxy-β-D-ribofuranosides 4 (N1) and 5 (N2) are evaluated
7 H -3,6-二氢-1,2,3-三唑并[4,5 - d ]嘧啶-7-一个2'-脱氧-β -D-核糖核苷(= 2'-脱氧-8-氮杂肌苷)3(N 3),15(N 2)和16(N 1)以及1,2,3-苯并三唑2'- O-甲基-β-或-α -D-描述了呋喃核糖核苷6(N 1)和24(N 1)。1,2,3-苯并三唑2'-deoxy-评估β -D核呋喃糖苷4(N 1)和5(N 2)。从核苷3 - 6,所述亚磷酰胺19,26A,26B,和28,制备和固相寡核苷酸合成中使用。在12聚体DNA双链体,化合物3示出了类似的暧昧碱基配对性质2'-脱氧肌苷(1),而核苷4 - 6示出了具有彼此强配对和鉴别非常少的4种正则DNA成分。
