  • A Simplified and Efficient Route to 2‘-<i>O</i>, 4‘-<i>C</i>-Methylene-Linked Bicyclic Ribonucleosides (Locked Nucleic Acid)

    can be prepared from D-glucose in multigram scale. Four different nucleobases were stereoselectively coupled to 8 using a modified Vorbrüggen procedure to give the corresponding 4'-C-branched nucleoside derivatives. Subsequent ring closing furnished the protected LNA nucleosides. The 5'-O-mesyl groups were efficiently displaced by nucleophilic substitution using sodium benzoate. Saponification of the
    描述了一种合成锁核酸(LNA)单体的新型有效方法。通过聚合合成制备了含有胸腺嘧啶,4-N-乙酰基和4-N-苯甲酰基胞嘧啶,6-N-苯甲酰腺嘌呤和2-N-异丁酰鸟嘌呤作为核碱基的LNA 5',3'-二醇。该方法基于使用常见的糖中间体1,2-二-O-乙酰基-3-O-苄基-4-C-甲磺酰氧基甲基-5-O-甲磺酰-D-赤型戊呋喃糖(8)可以从D-葡萄糖以克数制得。使用改良的Vorbrüggen程序将四个不同的核碱基立体选择性地偶联到8个核碱基上,得到相应的4'-C-支链核苷衍生物。随后的闭环提供了受保护的LNA核苷。使用苯甲酸钠通过亲核取代有效地置换了5'-O-甲磺酰基。将5'-苯甲酸酯皂化,然后催化除去3'-O-苄基,得到游离的LNA二醇。腺苷和胞苷的环外氨基被选择性地酰化,得到4-N-乙酰基或4-N-苯甲酰基-LNA-C和6-N-苯甲酰基-LNA-A。在制备2-N-异丁酰基-LNA-G期间,鸟

    on the bicyclo[2.2.1]heptane scaffold of locked nucleic acid (LNA) and tested them for both agonist and antagonist activity at the adenosine A(3) receptor. The design of these derivatives was based on the known A(3) agonist IB-MECA and related compounds. Modifications thus include the 5'-uronamides and N(6)-(3-iodobenzyl) derivatives. In this way we have prepared analogs of known A(3) agonists with
    我们基于锁定核酸(LNA)的双环[2.2.1]庚烷骨架制备了一系列腺苷类似物,并对其在腺苷A(3)受体上的激动剂和拮抗剂活性进行了测试。这些衍生物的设计基于已知的A(3)激动剂IB-MECA和相关化合物。因此,修饰包括5'-脲酰胺和N(6)-(3-碘苄基)衍生物。以这种方式,我们制备了已知的A(3)激动剂的类似物,其中糖环被限制在N-构象中。为了比较,我们还制备了IB-MECA的2'-O-甲基衍生物。LNA核苷无激动剂活性,但其中一些是有效的拮抗剂。IB-MECA的2'-O-甲基衍生物是与母体化合物具有相似效力的激动剂。

    A synthesis of [2.2.1]bicyclo nucleosides which is shorter and provides higher overall yields proceeds via the key intermediate of the general formula III, wherein R 4 and R 5 are, for instance, sulfonates and R 7 is, for instance, a halogen or an acetate. From compounds of the general formula II, such as 3-O-aryl-4-C-hydroxymethyl-1,2-O-isopropylidene-&agr;-D-ribofuranose, intermediates of the general formula III are suitable for coupling with silylated nucleobases. Upon one-pot base-induced ring-closure and desulfonation of the formed [2.2.1]bicyclo nucleoside, a short route to each the LNA (Locked Nucleic Acid) derivatives of adenosine, cytosine, uridine, thymidine and guanidine is demonstrated. The use of the 5′-sulfonated ring-closed intermediate also allows for synthesis of 5′-amino- and thio-LNAs. 1
    通过通式III的关键中间体进行合成[2.2.1]双环核苷,该方法较短且提供更高的总收率,其中R4和R5例如为磺酸盐,R7例如为卤素或醋酸盐。从通式II的化合物,例如3-O-芳基-4-C-羟甲基-1,2-O-异丙基亚-D-核糖,通式III的中间体适用于与硅化核苷碱进行偶联。通过一锅法碱催化环闭合和去磺酸化形成的[2.2.1]双环核苷,演示了腺嘌呤、胞嘧啶、尿嘧啶、胸腺嘧啶和鸟嘌呤的LNA(锁定核酸)衍生物的短路线。使用5'-磺酸化环闭合中间体还允许合成5'-氨基和硫代-LNA。
