A straightforward synthesis of 2′-functionalized uridines was developed based on a Cu-catalyzed cycloaddition of 2′-azido-2′-deoxyuridine and functionalized alkynes. The functions comprise biochemically important groups such as lipids, a fluorescent marker (Cy5 analogue), pentaacetylglucose, lysine and biotin, and are linked to the 2′-position of uridine by a 1,2,3-triazole ring.

基于 2'-叠氮基-2'-脱氧尿苷和官能化炔烃的 Cu 催化环加成,开发了 2'-官能化尿苷的直接合成。这些功能包括生物化学上重要的基团,例如脂质、荧光标记物(Cy5 类似物)、五乙酰葡萄糖、赖氨酸和生物素,并通过 1,2,3-三唑环连接到尿苷的 2'-位。许多核磁共振光谱研究表明,脂化的 2'-三唑基-2'-脱氧尿苷将自身锚定在磷脂膜中,而不影响双层中的分子顺序;极性部分——尿嘧啶、核糖和三唑——位于膜的脂质/水界面。
