3‐dideoxy‐3‐phthalimido‐D‐hexofuranose 3 which after acetylation at the anomeric hydroxy group is separated to give 4 and 5. Subsequent reaction with 5′‐substituted silylated uracil in the presence of TMS‐triflate results in three different 5′,6′‐di‐O‐acetyl‐2′,3′‐dideoxy‐3′‐phthalimido‐D‐hexofuranose nucleosides 7, 9, and 10 which were deprotected to give the corresponding 3′‐amino nucleosides 8, 11,
DBU(1,8-二氮杂双环[5,4,0]十一碳-7-烯)邻苯二甲酰亚胺盐与4,6-二-O-乙酰-2,3-二脱氧-醛-D-赤反式的迈克尔型加成-hex-2-enose 2 和伴随的乙酰位移产生 5,6-di-O-acetyl-2,3-dideoxy-3-phthalimido-D-hexfuranose 3 的阿拉伯和核糖异构体的异头混合物,在异头羟基被分离得到 4 和 5。随后在 TMS-三氟甲磺酸酯存在下与 5'-取代的甲硅烷基化尿嘧啶反应产生三种不同的 5',6'-二-O-乙酰基-2',3'-双脱氧‐3'-邻苯二甲酰亚胺-D-己基呋喃糖核苷 7、9 和 10 脱保护得到相应的 3'-氨基核苷 8、11 和 12。研究了化合物 7-12 对 HSV-1 和HIV-1。
