    Disclosed are O-protected compounds of the formula (I):wherein B is an optionally protected nucleobase, and R1-R3 are as described herein, a method of preparing such compounds, and a method of preparing oligonucleotides such as RNA starting from such compounds. The O-protected compounds have one or more advantages, for example, the 2'-O-protected compound is stable during the various reaction steps involved in oligonucleotide synthesis; the protecting group can be easily removed after the synthesis of the oligonucleotide, for example, by reaction with tetrabutylammonium fluoride; and/or the O-protected groups do not generate DNA/RNA alkylating side products, which have been reported during removal of 2'-O-(2-cyanoethyl)oxymethyl or 2'-O-[2-(4-tolylsulfonyl)ethoxymethyl groups under similar conditions.
    揭示了公式(I)中的O-保护化合物:其中B是可选择保护的核碱基,R1-R3如本文所述,一种制备这种化合物的方法,以及一种从这种化合物开始制备寡核苷酸(如RNA)的方法。这些O-保护化合物具有一个或多个优点,例如,2'-O-保护化合物在寡核苷酸合成中涉及的各种反应步骤中是稳定的;保护基在寡核苷酸合成后可以轻松去除,例如,通过与四丁基氟化铵反应;和/或O-保护基在类似条件下去除2'-O-(2-氰乙基)氧甲基或2'-O-[2-(4-甲苯磺酰基)乙氧甲基基团时不会产生已报道的DNA/RNA烷基化副产物。

    demonstrated by the single or double incorporation of a reversible pyrenylated uridine 2′-conjugate into an RNA sequence, the conjugation of 2′-O-aminooxymethyl ribonucleosides with aldehydes, including those generated from their acetals, provides reversible 2′-O-protected ribonucleosides for potential applications in the solid-phase synthesis of native RNA sequences.

    2'- O-氨基氧基甲基核糖核苷是通过在甲醇中用NH 4 F处理而从它们的3',5'-二甲硅烷基化的2'- O-邻苯二甲酰亚胺氧基甲基衍生物制备的。这些新型核糖核苷与 1-芘甲醛的反应导致以 69-82% 的产率有效形成稳定且可逆的核糖核苷 2'-缀合物。实际上,将这些缀合物暴露于 THF 中的0.5 M 四正丁基氟化铵 (TBAF) 会导致它们的亚氨基醚功能裂解,从而产生天然核糖核苷以及无害的腈副产物。相反,5-cholesten-3-one 或丹磺酰氯与 2'- O 的反应-氨基氧甲基尿苷提供永久性尿苷 2'-结合物,在用 TBAF 处理后基本保持完整。或者,5'- O-氨基氧基甲基胸苷通过其3'- O-乙酰丙酰基-5'- O-邻苯二甲酰亚胺氧基甲基前体的肼解制备。5'- O-氨基氧甲基胸苷的芘基化和 5'-偶联物对 TBAF 的敏感性进一步证明了这种核苷在永久性或可逆性修饰 DNA 序列方面的有用性。尽管
