Herein, we report the synthesis of novel 2′,2′,3′,3′-tetrafluorinated nucleoside analogs along with their phosphoramidate prodrugs. A tetrafluoro ribose moiety was coupled with different Boc/benzoyl-protected nucleobases under Mitsunobu conditions. After deprotection, tetrafluorinated nucleosides 13b, 14b, 20b-22b were reacted with phenyl-(isopropoxy-l-alaninyl)-phosphorochloridate to afford corresponding
在这里,我们报告了新型2',2',3',3'-四氟核苷类似物及其氨基磷酸酯前药的合成。在Mitsunobu条件下,将四氟核糖部分与不同的Boc /苯甲酰基保护的核碱基偶联。脱保护后,使四氟化核苷13b,14b,20b - 22b与苯基-(异丙氧基-1-丙氨酰)-磷酰氯反应,得到相应的单磷酸酯前药24b - 28b。对所有合成的化合物均针对几种DNA和RNA病毒进行了评估,包括HIV,HBV,HCV,埃博拉和Zika病毒。
