    The invention relates to a novel strategy for the synthesis of Locked Nucleic Acid derivatives, such as α-L-oxy-LNA, amino-LNA, α-L-amino-LNA, thio-LNA, α-L-thio-LNA, seleno-LNA and methylene LNA, which provides scalable high yielding reactions utilising intermediates that also can produce other LNA analogues such as oxy-LNA. Also, the compounds of the formula X are important intermediates that may be reacted with varieties of nucleophiles leading to a wide variety of LNA analogues. (Formula I)
    该发明涉及一种用于合成锁定核酸衍生物的新策略,例如α-L-氧基-LNA、基-LNA、α-L-基-LNA、基-LNA、α-L-基-LNA、基-LNA和亚甲基-LNA,该策略利用中间体进行可扩展高产率反应,这些中间体还可以产生其他LNA类似物,如氧基-LNA。此外,式X的化合物是重要的中间体,可以与多种亲核试剂发生反应,从而形成各种LNA类似物。

    significantly improved synthetic routes to 2'-amino-LNA (locked nucleic acid). The optimal route is convergent with the synthesis of LNA monomers ("2'-oxy-LNA") via a common intermediate obtained by a mild deacetylation for the liberation of the 2'-hydroxy group to give compound 23 without the concomitant ring closure that affords the 2'-oxy-LNA skeleton. After inversion of the stereochemistry at C2' and triflate
    在本文中,我们提出了经过修订和显着改进的合成途径,以合成2'-基LNA(锁定核酸)。最佳途径与通过普通中间体合成LNA单体(“ 2'-氧基-LNA”)收敛,该中间体是通过轻度脱乙酰作用而释放出2'-羟基而得到的化合物23,而没有伴随的闭环提供2'-氧-LNA骨架。在颠倒C2'处的立体化学并在2'-羟基处形成三氟甲磺酸酯后,获得了新的通用中间体16,该中间体可轻松进入一系列其他类似物,例如通过引入导致2'-基的亲核试剂-LNA结构。用叠氮化物取代三氟甲磺酸酯后,碱性还原得到所需的2'-基-LNA结构,即化合物18。

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

    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'-基和代-LNA。
