Adenosine cyclic 3′,5′-phosphoramidate was synthesized by reacting adenosine cyclic 3′,5′-phosphate with POCl3, in trimethyl phosphate for 1 h at O°C, followed by in situ treatment of the reaction mixture with a suspension of (NH4)2CO3 in anhydrous DMF or pyridine or DMF/pyridine mixture for 30 min at 25° C. Diastereoisomers (P)- and (P)- the relative quantities of which depended on the solvent of
腺苷环3',5'-磷酸氨基甲酸酯的合成方法是:将腺苷环3',5'-磷酸与POCl 3在磷酸三甲酯中于0°C反应1小时,然后用悬浮液原位处理反应混合物。 (NH 4)2 CO 3在无水DMF或吡啶或DMF /吡啶混合物中在25°C下放置30分钟。非对映异构体(P)-和(P)-的相对量取决于(NH 4)2的溶剂通过反相分配色谱分离CO 3处理。(R P)-和(S的水解P)-继续进行(在0.1 N HCl中为90%,在0.1 N NaOH中为100%)-POC键断裂。
