electrophilic activation of 5′-phosphorothioate nucleotides. The treatment of phosphorothioate with 2,4-dinitrochlorobenzene (DNCB) efficiently afforded the key activated species, electrophilic thioester nucleotides (EPT-Ns), which were coupled with various phosphate reagents to afford the target nucleoside oligophosphates, including an mRNA cap analog.
我们在此报告了一种基于 5'-硫代磷酸酯核苷酸亲电激活的核苷寡磷酸酯的新合成方法。用 2,4-二硝基氯苯 (DNCB) 处理硫代磷酸酯有效地提供了关键的活化物质,亲电子硫酯核苷酸 (EPT-Ns),它与各种磷酸盐试剂偶联以提供目标核苷低聚磷酸盐,包括 mRNA 帽类似物。
