oligonucleotide analogue containing [2.2.1]bicyclo nucleoside monomers. A novel and significantly improved method for convergent synthesis of LNA [2.2.1]bicyclo nucleosides using a 4-C-tosyloxymethyl-1, 2-di-O-acetyl furanose as a key synthon is described. In addition, an alternative, robust linear approach allowing selective formation of the desired [2.2.1]bicyclo LNA nucleosides via a tricyclic nucleoside
LNA(锁定核酸)是一种新型的寡核苷酸类似物,含有[2.2.1]双环核苷单体。描述了一种新颖且显着改进的方法,该方法使用4-C-甲苯磺酰氧基甲基-1,2-二-O-乙酰基呋喃糖作为关键合成子,聚合合成LNA [2.2.1]双环核苷。此外,介绍了一种替代的,稳健的线性方法,该方法允许通过三环核苷中间体选择性形成所需的[2.2.1]双环LNA核苷。
