A novel method of transformation of HOCH2 group to FCH2 was successfully applied to the preparation of fluorine-containing pyrimidine acyclic nucleoside phosphonates (FPMP compounds) such as (S)- and (R)-1-[3-fluoro-2-(phosphonomethoxy)propyl]thymine (7a, 7b) (FPMPT). The key displacement of hydroxy group with fluorine in 1-2-[(diisopropoxyphosphoryl)- methoxy]-3-hydroxypropyl}-4-methoxy-5-methylpyrimidin-2(1H)-one (5a, 5b) was performed using perfluorobutane-1-sulfonyl fluoride in the presence of DBU. Novel pyrimidine acyclic nucleoside phosphonates were investigated as inhibitors of thymidine phosphorylase.
一种将HOCH2基团转化为FCH2的新方法成功应用于氟含量嘧啶无环核苷酸磷酸酯(FPMP化合物)的制备,例如(S)-和(R)-1-[3-氟-2-(磷酸甲氧基)丙基]胸腺嘧啶(7a,7b)(FPMPT)。在1-2-[(二异丙氧磷酰)-甲氧基]-3-羟基丙基}-4-甲氧基-5-甲基嘧啶-2(1H)-酮(5a,5b)中,关键的羟基与氟原子的取代反应是在DBU存在下使用全氟丁烷-1-磺酰氟进行的。新型嘧啶无环核苷酸磷酸酯被研究作为胸腺嘧啶磷酸酶的抑制剂。
