group of 2′,3′,5′-tri-O-acetylguanosine by treatment with the corresponding trityl chlorides in pyridine to afford the N2-tritylated guanosine derivatives in high yields. Similarly, the N6-tritylated adenosine derivatives were synthesized. The stability of the three kinds of trityl groups under acidic conditions were described. The MMTr and Tr groups were found to be suitable for the protection of the 2-amino
将三苯甲基 (Tr)、4-甲氧基三苯甲基 (MMTr) 和 4,4'-二甲氧基三苯甲基 (DMTr) 基团引入 2',3',5'-三-O-乙酰鸟苷的 2-氨基中。相应的三苯甲基氯在吡啶中以高产率提供 N2-三苯甲基化鸟苷衍生物。类似地,合成了 N6-三苯甲基化的腺苷衍生物。描述了三种三苯甲基在酸性条件下的稳定性。发现MMTr和Tr基团适合在寡核苷酸合成中保护鸟苷的2-氨基。合成了适当保护的 N2-三苯甲基鸟苷 5-二硫代磷酸酯衍生物并将其用于 pGpUpU 的合成。
