report the synthesis and properties of nucleoside derivatives acylated by 2-(trimethylsilyl)benzoyl (TMSBz) that proved to be extremely stable under basic conditions when introduced into the 5′-hydroxyl group of thymidine, the 4-amino group of deoxycytidine and the 2′-hydroxyl group of uridine. In particular, 2′-O-TMSBz-uridine could be isolated and was more stable in pyridine, while it isomerized in CH2Cl2
我们报道了被2-(三甲基甲硅烷基)苯甲酰基(TMSBz)酰化的核苷衍生物的合成和性质,当将其引入胸苷的5'-羟基,脱氧胞苷的4-氨基和尿苷的2'-羟基。特别是,可以分离出2' - O -TMSBz-尿苷,并在吡啶中更稳定,而在Et 3 N存在下在CH 2 Cl 2中异构化,生成2'-O-和3'的混合物。 -O-酰化的物种。
