A di(pyrimidine nucleoside 5′-)polyphosphate is synthesized by converting a pyrimidine nucleoside 5′-triphosphate into a pyrimidine nucleoside 5′-cyclic triphosphate by use of a condensing agent, and subsequently reacting the pyrimidine nucleoside 5′-cyclic triphosphate with a pyrimidine nucleotide in the presence of a salt of a metal selected from among magnesium, manganese, and iron.
Through the method of the invention, a di(pyrimidine nucleoside 5′-)polyphosphate can be synthesized from an unprotected pyrimidine nucleoside 5′-phosphate serving as a starting material at a synthesis yield of 50% or higher. Therefore, the method of the invention is suitable for large-scale synthesis of a di(pyrimidine nucleoside 5′-)polyphosphate.
通过使用缩合剂将嘧啶核苷酸5'-三磷酸转化为嘧啶核苷酸5'-环三磷酸,然后在镁、锰、铁等金属盐的存在下将嘧啶核苷酸5'-环三磷酸与嘧啶核苷酸反应,可以合成一种二(嘧啶核苷酸5'-)聚磷酸。通过本发明的方法,可以从作为起始物的未保护的嘧啶核苷酸5'-磷酸合成出50%或更高的产率的二(嘧啶核苷酸5'-)聚磷酸。因此,本发明的方法适用于大规模合成二(嘧啶核苷酸5'-)聚磷酸。
