The synthesis of dideoxynucleosides (ddNs) or didehydro-dideoxynucleosides (d4Ns) from nucleosides has been extensively reviewed. While previously described methods are based on the modification of the 2′- and/or 3′-OH group of the intact ribose moiety, the use of a ring-closing metathesis (RCM) for the formation of the unsaturated cyclic system of nucleosides could be a straightforward approach to
从核苷合成双脱氧核苷 (ddNs) 或双脱氢-双脱氧核苷 (d4Ns) 已被广泛审查。虽然之前描述的方法是基于完整核糖部分的 2'-和/或 3'-OH 基团的修饰,但使用闭环复分解 (RCM) 来形成核苷的不饱和环状系统可以是 d4Ns 的直接方法。因此,作为我们药物标签计划的一部分,本文报告了 2',3'-didehydro-2',3'-dideoxyuridine (d4U) 和 [1',2',3',4',5 '-13C5,6-13C,1,3-15N2]d4T 使用 RCM 协议。本文讨论了核苷二烯的制备和钌基复分解催化剂的活性。(© Wiley-VCH Verlag GmbH & Co.
