The chemical synthesis of 2′-amino-2′-deoxyribonucleosides of uracil, cytosine, adenine, and guanine, and their conversion into suitably protected 3′-phosphoramidite building blocks 35–40 for oligonucleotide synthesis are described. The aglycone and the 2′-amino functions were protected using the 2-(4-nitrophenyl)ethoxycarbonyl (npeoc) group. The synthesis of the 3′-O-succinyl (3′-O-(3-carboxypropanoyl))-substituted
化学合成的尿嘧啶,胞嘧啶,腺嘌呤,鸟嘌呤和2'-氨基-2'-脱氧核糖核苷,和其转化为适当保护的3'-亚磷酰胺构建模块35 - 40用于寡核苷酸合成进行说明。使用2-(4-硝基苯基)乙氧羰基(npeoc)基团保护糖苷配基和2'-氨基官能团。3'- O-琥珀酰基(3' - O-(3-羧基丙酰基))取代的起始核苷41的合成描述了1,8-二氮杂双环[5.4.0]十一碳-7-烯(DBU)脱保护过程中预期迁移的溶液和固相行为,并对其进行了研究。使用新的结构单元制备了寡核苷酸,并通过紫外熔融技术研究了它们的杂交特性。
