    Process Development for the Synthesis of 5′-O-(4,4′-Dimethoxytrityl)-N2-isobutyryl-2′-O-(2-methoxyethyl)-guanosine—A Potential Precursor for the Second Generation Antisense Oligonucleotides: An Improved Process for the Preparation of 2′-O-Alkyl-2,6-diaminopurine Riboside
    摘要:
    An efficient four step process for the preparation of 5'-O-(4,4'-dimethoxytrityl)-N-2-isobutyryl-2'-O-(2-methoxyethyl)-guanosine I was developed. Direct 2'-O-alkylation of 2,6-diaminopurine riboside 2 was accomplished via inexpensive and commercially available reagents such as KOH, DMSO and alkyl halides at room temperature in 4-6 hrs. Pure 2'-O-(2-methoxyethyl)-DAPR 3 was isolated by crystallization from methanol. Enzymatic deamination of 3 followed by selective N-2-isobutyrylation and 5'-O-dimethoxytritylation furnished desired 1 in high yield and purity. Fully optimized four step synthetic process has been scaled up to the pilot plant level.

  • Synthesis of 2‘-<i>O</i>-Methoxyethylguanosine Using a Novel Silicon-Based Protecting Group

    A short and efficient synthesis of 2'-O-methoxyethylguanosine (8) is described. Central to this strategy is the development of a novel silicon-based protecting group (MDPSCl(2), 2) used to protect the 3',5'-hydroxyl groups of the ribose. Silylation of guanosine with 2 proceeded with excellent regioselectivity and in 79% yield. Alkylation of the 2'-hydroxyl group of 6 proceeded with methoxyethyl bromide
    描述了2'-O-甲氧基乙基鸟苷(8)的短而有效的合成。该策略的核心是开发一种新型的基于的保护基(MDPSCl(2),2),用于保护核糖的3',5'-羟基。用2进行的鸟苷硅烷基化具有极好的区域选择性,产率为79%。用甲氧基乙基化物和NaHMDS进行6的2′-羟基的烷基化,以85%的收率得到化合物7,而甲硅烷基保护基没有任何明显的裂解,也不需要保护鸟嘌呤碱基部分。最终,使用TBAF实现了7的脱保护并且以97%的产率产生了8。

    Silylating reagents having a group other than a divalent oxygen separating two silyl groups provide regioselective protection of reactive groups under robust conditions, such as basic conditions used in alkylation, acylation and deoxygenation. In particular, silylating reagents having a group other than oxygen separating two silyl groups are useful for protecting two hydroxy groups of a ribonucleic or deoxyribonucleic acid. Alkylation of a 2′-hydroxy group of a ribonucleoside protected with the inventive silylating agents in the presence of an excess of a mild hindered base such as sodium HMDS may be carried out without protecting the exocyclic amine and oxo functionalities of nucleobases.
    具有除了双价氧以外的其他基团的基化试剂,在强韧条件下提供对反应基团的区域选择性保护,例如烷基化、酰化和脱氧等碱性条件。特别是,具有除氧以外的基团分隔两个基团的基化试剂对于保护核糖核酸脱氧核糖核酸的两个羟基是有用的。在存在过量轻微阻碍碱(如HMDS)的情况下,可在创新的基化试剂保护的核糖核苷酸的2'-羟基上进行烷基化,而无需保护嘌呤碱基的外环胺基和羟基官能团。

    An optimized process to synthesize DMT protected 2 '-O-methoxyethylguanosine is described. A key step involves the enzymatic deamination of a mixture of alkylated products to selectively afford the desired material without resorting to chromatography for purification. This approach was scaled up to kilogram quantities for use in oligonucleotide therapeutics. [Formula: see text].
