The chemical syntheses of the phosphorothioate of (2′–5′)adenylate dimer (see 6a, 6b) and trimer (see 11a, 11b, 12a, 12b) as well as of their 5′-monophosphates (see 15a, 15b, 16a, 16b) using the phosphoramidite method are described. The resulting diastereoisomer mixtures were separated into the pure components by chromatographical means. All synthetic intermediates were characterized by TLC, elemental
(2'-5')腺苷酸二聚体(参见6a,6b)和三聚体(参见11a,11b,12a,12b)的硫代磷酸酯及其5'-单磷酸酯(参见15a,15b,16a)的化学合成图16b)描述了使用亚磷酰胺方法。通过色谱方法将得到的非对映异构体混合物分离成纯组分。所有合成中间体均通过TLC,元素分析,UV和1 H-NMR光谱进行表征。
