Immobilized and fully protected oligodeoxynucleotides containing a 4-(1,2,4-triazolyl)-thymidine residue at a predetermined position were prepared according to a well-established phosphite triester methodology using 2-cyanoethyl phosphoramidites of a 4-(1,2,4-triazolyl)-substituted thymidine and standard protected nucleosides. Treatment of the immobilized oligomer with methanol, ethanol or n-propanol
根据公认的亚磷酸酯三酯方法,使用4-(1,2,4-,1,2,3-三氟乙烷基)的2-氰基乙基亚磷酰胺,制备在预定位置上含有4-(1,2,4-三唑基)-胸苷残基的固定化和完全保护的寡脱氧核苷酸。 4-三唑基)-取代的胸苷和标准保护的核苷。在DBU存在下于50℃用甲醇,乙醇或正丙醇处理固定的低聚物,得到相应的含有4-甲氧基,4-乙氧基-或4-正丙氧基胸苷残基的寡核苷酸。
