A series of new 5-(1-hydroxy-2-iodoethyl)-2'-deoxyuridine and uridine compounds (11, 16) was synthesized by the regiospecific addition of HOI to the vinyl substituent of 5-vinyl-2'-deoxyuridine (10a), 5-vinyl-2'-fluoro-2'-deoxyuridine (10b), 5-vinyluridine (10c), and (E)-5-(2-iodovinyl)-2'-deoxyuridine (4b). Treatment of the iodohydrins 11a-c with methanolic sulfuric acid afforded the corresponding
通过将HOI的区域特异性加成到5-乙烯基-2'-脱氧尿苷的乙烯基取代基上来合成一系列新的5-(1-羟基-2-碘乙基)-2'-脱氧尿苷和尿苷化合物(11,16)( 10a),5-乙烯基-2′-氟-2′-脱氧尿苷(10b),5-乙烯基尿苷(10c)和(E)-5-(2-碘乙烯基)-2′-脱氧尿苷(4b)。用甲醇硫酸处理碘代醇11a-c,得到相应的5-(1-甲氧基-2-碘乙基)衍生物(12a-c)。相反,5-(1-羟基-2-碘乙基)-2'-脱氧尿苷(11a)与碳酸钠在甲醇中反应,得到5-(1-羟基-2-甲氧基乙基)-2'-脱氧尿苷( 13)和2,3-二氢-3-羟基-5-(2'-脱氧-β-D-呋喃呋喃糖基)-呋喃并[2,3-d]嘧啶-6(5H)-(14)。活性最高的化合物5-(1-甲氧基-2-碘乙基)-2'-脱氧尿苷(12a,ID50 = 0。1微克/毫升)的抗病毒活性(HSV-1)比5-(1-羟基
