step at C (5) of 5-hydroxyuridine (4a) or 5-hydroxy-2′-deoxyuridine (4b) by certain primary amines led to the synthesis of two novel C(5)-N-spin-labeled nucleoside analogs and to several C(5)-N-aryl adducts. Substitution by 4-amino-2,2,6,6-tetramethylpiperidinooxyl (3) at C(5) of 4a or 4b led to the spin-labeled nucleosides 5-[(1-oxyl-2,2,6,6-tetramethyl-4-piperidinyl)amino]uridine and -2′-deoxyuridine
在某些步骤中,某些伯胺在C(5)的5-羟基尿苷(4a)或5-羟基-2'-脱氧尿苷(4b)的直接引入N原子导致合成了两个新颖的C(5)- N-spin标记的核苷类似物和几个C(5)-N-芳基加合物。在4a或4b的C(5 )处被4-氨基-2,2,6,6-四甲基哌啶子氧基(3)取代导致自旋标记的核苷5-[(1-氧基-1,2,6,6-四甲基-4-哌啶基)氨基]尿苷和-2'-脱氧尿苷(分别为2a和2b)。类似的C(5)取代的苯胺加合物5-苯胺基尿苷(5a)和5-苯胺基-2'-脱氧尿苷(5b)和p还制备了甲苯胺加合物5-(对甲苯胺基)尿苷(6a)和5-(对甲苯胺基)-2-脱氧尿苷(6b)。另外,报道了其中一些类似物的抗病毒和抗代谢活性的结果。
