  • 一种胞嘧啶核苷的制备方法
    申请人:中国科学院上海药物研究所
    公开号:CN110511258A
    公开(公告)日:2019-11-29
    本发明提供了一种制备胞嘧啶核苷1的方法,其包括如下步骤:(1)化合物6与化合物7,可在四氯化锡的存在下进行缩合反应并生成化合物8;(2)去除化合物8中的alpha‑异构体和其他反应杂质,得到beta‑异构体的化合物8;(3)beta‑异构体的化合物8在醇类溶剂存在下发生脱保护反应,然后与盐酸发生成盐反应得到化合物1。本发明从廉价的,具有混合异头碳构型的原料7,特别是原料7a,以及略过量的碱基6,特别是碱基6a出发,即可高beta‑立体选择性地获得核苷化合物8;核苷化合物8可通过简单的打浆方法除去微量alpha‑化合物8异构体杂质;随后针对beta‑化合物8的脱保护和成盐反应均具有较高收率,因此本方法可降低化合物1的生产成本。

    gemcitabine synthesis, highly beta-stereoselective and high yielding TBAI catalyzed N-glycosylation was achieved with N4-Bz cytosine and anomeric mixture of 2,2‘-difluororibose mesylate donor. The subsequent global deprotection gave gemcitabine efficiently. Meanwhile, the anomeric chloride intermediate and fluoride-displaced side products of this N-glycosylation were identified, too. This new glycosylation
    通过在吉西他滨合成的糖基化步骤中各种N 4保护的胞嘧啶生物的系统比较,使用N 4 -Bz胞嘧啶和2,2'-二核糖甲磺酸酯的异头混合物,实现了高β-立体选择性和高产率的TBAI催化的N-糖基化。捐赠者。随后的整体脱保护有效地赋予了吉西他滨。同时,还鉴定出该N-糖基化的异头化物中间体和化物置换的副产物。这种新的糖基化方法揭示了N 4的重要性嘧啶核苷立体选择性制备中的β-保护,也为吉西他滨目前的工业生产提供了潜在的替代方法。

    Glycosylation of silylated pyrimidines using a phenyl 2-deoxy-3-O-(N-benzoyl)carbamoyl-1-thio-D-erythro-pentofuranoside yielded 2-deoxy-β-ribonucleosides in good yields with excellent anomeric selectivity. This prototype 3-O-carbamate directing group was readily formed and removed in high yields.

    Treatment of 1, 2 : 5, 6-di-O-isopropylidene-3-amino-3-deoxy-α-D-allofuranose (1) with trifluoroacetic anhydride afforded crystalline 3-trifluoroacetamido derivative (2) in good yield. Selective removal of the 5, 6-O-isopropylidene group of 2 by treatment with 70% acetic acid followed by oxidation with periodate and subsequent reduction with sodium borohydride gave crystalline 1, 2-O-isopropylidene-3-deoxy-3-trifluoroacetamido-α-D-ribofuranose (3) in good yield. p-Nitrobenzoylation of 3 followed by acetolysis afforded crystalline 1, 2-di-O-acetyl-3-deoxy-3-trifluoroacetamido-5-O-p-nitrobenzoyl-β-D-ribofuranose (5). Coupling of the resulting 1-O-acetyl sugar with bis-trimethylsilylated derivatives of N4-acyl-5-fluorocytosines, N4-acylcytosines, 5-fluorouracil and N4-acetyl-5-methylcytosine using SnCl4 afforded the corresponding fully acylated nucleosides (7). Saponification of 7 gave 3-amino-3-deoxy-β-D-ribonucleosides (8a-8d). Alternatively, 2, 4-dimethoxy-5-methylpyrimidine was also coupled with 5 followed by treatment with ammonia to give 8d. The nucleosides (8a-8d) thus obtained were examined for cytostatic effect on mouse leukemic L5178Y cells. The compounds tested were active against this system and their ED50 values were 0.7 μg/ml, 7 μg/ml, 16 μg/ml and 60 μg/ml, respectively.
    1, 2 : 5, 6-二-O-异丙叉-3-基-3-脱氧-α-D-阿洛呋喃糖(1)经过三氟乙酸酐处理后,以良好产率得到了晶体状的3-三乙酰胺基衍生物(2)。通过用70%乙酸选择性去除2的5, 6-O-异丙叉基团,随后用过碘酸盐氧化和后续用硼氢化钠还原,以良好产率得到了晶体状的1, 2-O-异丙叉-3-脱氧-3-三乙酰胺基-α-D-核呋喃糖(3)。3经过对硝基苯甲酰化后,再经乙酸分解处理,得到了晶体状的1, 2-二-O-乙酰-3-脱氧-3-三乙酰胺基-5-O-对硝基苯甲酰-β-D-核呋喃糖(5)。利用SnCl4将所得的1-O-乙酰糖与N4-酰基-5-胞嘧啶、N4-酰基胞嘧啶、5-尿嘧啶和N4-乙酰-5-甲基胞嘧啶的双-三甲基基化衍生物偶联,得到了相应的全酰化核苷(7)。7经过皂化处理后得到了3-基-3-脱氧-β-D-核苷(8a-8d)。此外,2, 4-二甲氧基-5-甲基嘧啶也与5偶联,随后用处理得到了8d。所得到的核苷(8a-8d)被检测了对小鼠白血病L5178Y细胞的细胞抑制效应。测试的化合物对此系统具有活性,其ED50值分别为0.7 μg/ml、7 μg/ml、16 μg/ml和60 μg/ml。

    Coupling reaction between 2-α-phenylthio-2,3-dideoxyribose and silylated pyrimidine bases in the presence of SnCl4 proceeded stereoselectively to give the β-anomers. These nucleosides were converted to 2′,3′-dideoxy-2′,3′-didehydronucleosides by oxidation followed by thermal elimination.
    在SnCl4存在下,2-α-苯基-2,3-双脱氧核糖嘧啶碱基的耦合反应以立体选择性方式进行,得到β-异构体。这些核苷随后通过氧化后进行热消除,转化为2′,3′-双脱氧-2′,3′-双脱氢核苷。
