A new 2′-OH protecting group, [2,2-dimethyl-2-(2-nitrophenyl)acetyl]oxy} methyl (DAM), has been successfully applied to RNA oligonucleotides synthesis with high coupling efficiency. The 2′-O-DAM method is fully compatible with reagents and conditions employed in automated solid phase synthesis of RNA. Moreover, it can be easily removed via reduction in near-neutral solution.
一种新的2'-OH保护基,[2,2-二甲基-2-(2-硝基苯基)乙酰基]氧基}甲基(DAM)已成功地用于RNA寡核苷酸的合成,具有很高的偶联效率。2'- O- DAM方法与RNA自动固相合成中使用的试剂和条件完全兼容。此外,可以通过减少接近中性的溶液轻松地将其除去。
