The racemic carbocyclic 2'-fluoroarabinosyl pyrimidine nucleosides 8, 9 (C-FIAU), 12, and 13 (C-FMAU) and the 2'-fluororibosyl pyrimidine nucleosides 17, 20, and 21 were prepared from their respective protected 2'-fluoro amino diols 5 and 14. The carbocyclic 2'-2'-difluorothymidine analogue 27 was obtained from the protected difluoro amino diol 24 which was prepared from the ketone 23 and (diethylamino)sulfur
外消旋碳环的2'-氟阿拉伯糖基嘧啶核苷8、9(C-FIAU),12和13(C-FMAU)和2'-氟核糖基嘧啶核苷17、20和21是由它们各自的受保护的2'-氟代氨基二醇5和14。碳环2'-2'-二氟胸苷类似物27是从被保护的二氟氨基二醇24获得的,该二氟氨基二醇24是由酮23和(二乙基氨基)三氟化硫(DAST)制备的。由受保护的6'-氟氨基二醇30和36合成手性碳环2'-脱氧-6'-氟尿苷33、34、38和39,它们是通过还原叠氮化物28和35制备的。C-FMAU (13)和C-FIAU(9)在体外对HSV-1有活性,ID50值分别为4.4和11微克/ mL,但对HSV-2无活性。
