A general and high-yielding synthesis of nucleoside 5′-triphosphates (NTPs) and nucleoside 5′-diphosphates (NDPs) from protected nucleoside 5′-phosphoropiperidates promoted by 4,5-dicyanoimidazole (DCI) has been developed. 31P NMR tracing experiments showed that the sequential deprotection and coupling reactions were exceptionally clean. The phosphoropiperidate exhibited superior reactivity to the
已经开发了由4,5-二氰基咪唑(DCI)促进的受保护的核苷5'-磷酸哌啶酸酯合成核苷5'-三磷酸酯(NTPs)和核苷5'-二磷酸酯(NDP)的通用且高产率的方法。31 P NMR示踪实验表明,顺序的脱保护和偶联反应非常干净。磷酸哌啶酯对DCI促进的NTP / NDP合成显示出优于常规磷酸吗啉酸酯的反应性。实验结果表明,取决于焦磷酸盐和磷酸盐的不同亲核性,DCI激活的机制对于NTP和NDP合成可能是独特的。
