The present invention is directed to RNA monomers comprising O-acetal levulinyl protecting groups at the 2′ and/or the 5′-hydroxy functionalities of the ribose moiety. Said monomers may be incorporated into oligoribonucleotides or RNA polynucleotides. Furthermore, the invention is directed to methods for the synthesis of said RNA monomers, oligoribonucleotides and RNA polynucleotides, as well as methods for their deprotection and methods for the use of said compounds and compositions comprising said compounds. In particular, such compounds and compositions comprising them are used in methods for light-directed synthesis of RNA microarrays.
本发明涉及在核糖分子的 2′和/或 5′-羟基官能团上含有 O-乙缩醛乙酰基保护基团的 RNA 单体。所述单体可与寡核苷酸或 RNA 多核苷酸结合。此外,本发明还涉及合成所述 RNA 单体、寡核苷酸和 RNA 多核苷酸的方法,以及它们的脱保护方法和使用所述化合物和包含所述化合物的组合物的方法。特别是,这些化合物和包含它们的组合物可用于 RNA 微阵列的光导合成方法。
