bicyclic furanosyl skeleton with a locked conformation. The phosphoramidite derivatives and were used for automated synthesis of 9-mer DNA and [small alpha]-L-LNA oligonucleotides containing the [small alpha]-L-LNA-type C-aryl monomers ([small alpha]L)Ph(L) and ([small alpha]L)Py(L) containing a phenyl and pyrenyl aglycon, respectively. Thermal denaturation studies showed universal base pairing behavior
含有苯基和1-吡啶基糖苷配基的2 [伯或分钟] -O,4 [伯或分钟] -C-亚甲基-[小α] -1-核糖呋喃糖基衍生物的合成,即新型[小α] -1-核糖已经完成了配置的LNA-型C-芳基核苷的制备。关键的合成步骤包括在四氢呋喃醛上的立体选择性格氏反应,将所得醇构型转化为醇,以及伴随的Mitsonobu环化反应,为所需的双环呋喃糖骨架提供锁定的构象。亚磷酰胺衍生物被用于9-mer DNA和含有[小α-L-LNA-型C-芳基单体([小αL])Ph(L)的小[α] -L-LNA寡核苷酸的自动合成。 )和(小αL)Py(L)分别含有苯基和pyr基糖苷配基。
