3-dideoxy-beta- D-erythro-pentofuranose (3), in the presence of trimethylsilyl triflate as a catalyst, to give the corresponding 3'-phthalimido-2',3'-dideoxynucleosides 5a-f and 6 which on treatment with 33% methylamine-ethanol afforded the corresponding 3'-amino-2',3'-dideoxynucleosides 7a-f and 8 in high yields. Compound 7d showed colony inhibition when tested against human epidermoid cervical cancer cells
5-烷氧基甲基尿嘧啶2a-c已通过5-羟基甲基尿嘧啶(1)的酸催化醚化反应制备。将化合物1、2a-c,5-甲氧基甲基-和5-苄氧基甲基-尿嘧啶甲硅烷基化并与1,5-二-O-乙酰基-3-邻苯二甲酰亚胺基-2,3-二脱氧-β-D-赤型戊呋喃糖( 3),在三氟甲磺酸三甲基甲硅烷基酯作为催化剂的存在下,得到相应的3'-邻苯二甲酰亚胺基-2',3'-二脱氧核苷5a-f和6,将其用33%甲胺-乙醇处理后得到相应的3'-氨基-2',3'-二脱氧核苷7a-f和8的产量很高。当针对人表皮样宫颈癌细胞进行测试时,化合物7d显示出集落抑制作用。核苷5a-e,7a-f和8没有显示出对HIV-1的任何显着活性。
