2'-Deoxy-2'-C-trifluoromethyl-beta-D-ribonucleoside derivatives bearing the five naturally occurring acid bases have been synthesized. All these derivatives were prepared by glycosylation reactions of purine and pyrimidine bases with a suitable peracylated 2-deoxy-2-C-trifluoromethyl sugar precursor to afford anomeric mixtures of protected nucleosides. After separation and deprotection, the resulting beta-nucleoside
已经合成了带有五个天然存在的酸碱的2'-脱氧-2'-C-三氟甲基-β-D-核糖核苷衍生物。所有这些衍生物是通过嘌呤和嘧啶碱基与合适的过酰基化的2-脱氧-2-C-三氟甲基糖前体的糖基化反应制备的,以提供被保护的核苷的端基异构体混合物。分离和脱保护后,测试所得的β-核苷类似物对HIV,HBV和几种RNA病毒的活性。但是,这些化合物均未显示出显着的抗病毒活性或细胞毒性。
