  摘要：

  This invention relates to an oligonucleotide comprising one or more 2'-modified nucleosides, wherein the 2'-position of the nucleoside has a structure of formula (I). The invention also relates to a pharmaceutical composition comprising the oligonucleotide described herein and a method of reducing or inhibiting the expression of a target gene by administering to the subject a therapeutically effective amount of the oligonucleotide described herein. The invention also relates to a method of bioactivating an oligonucleotide comprising one or more 2'-modified nucleosides, wherein the 2'-position of the nucleoside is modified by a bio-cleavable linking group, wherein the bio-cleavable linking group comprises acetal, disulfide, carbamate, amide, sulfonamide, a biocleavable carbohydrate linker, or combinations thereof, said method comprising the step of: exposing the oligonucleotide to a physiological condition that causes the bio-cleavable linking group to be cleaved from the 2'-modified nucleoside, thereby regenerating the 2'-OH group of the nucleoside.

  is described for unsymmetrical disulfide synthesis from two different thiols using 1-chlorobenzotriazole (BtCl) as oxidant. The mechanism of the coupling involves in situ trapping of the sulfenyl chloride intermediate R1SCl by nucleophilic benzotriazole (BtH) to form R1SBt, which protects R1SCl from forming the homodimer R1SSR1. The methodology is applicable to all types of thiol (aliphatic, aromatic

  描述了一种高产，低温的一锅法，用于使用1-氯苯并三唑（BtCl）作为氧化剂由两种不同的硫醇合成不对称的二硫键。偶联的机制包括通过亲核苯并三唑（BtH）原位捕获亚磺酰氯中间体R 1 SCl形成R 1 SBt，从而保护R 1 SCl避免形成同型二聚体R 1 SSR 1。该方法适用于所有类型的硫醇（脂族，芳族，杂芳族），并为脂族-脂族偶联开发了一种变体。差异性的N-保护的半胱氨酸偶合，以高收率（90％）提供不对称的胱氨酸衍生物，该模型可作为含半胱氨酸的肽单分子间偶联形成肽二硫键异二聚体的模型。由于条件温和，因此注意到芳香族-芳香族二硫化物合成中的交换最少。
