fluoromethylene, and difluoromethylene analogues of the deoxynucleotides 2′-deoxyadenosine 5′-triphosphate and thymidine 5′-triphosphate have been prepared. by reaction between the bisphosphonic acid and the appropriate 5′-O-tosyl deoxynucleoside giving analogues of the 2′-deoxynucleoside 5′-diphosphate. The γ-phosphate is added subsequently either via activation of P-2 of the dNDP as its morpholidate followed by
制备了脱氧核苷酸2'-脱氧腺苷5'-三磷酸和胸苷5'-三磷酸的P 1,P 2取代的亚甲基,氟亚甲基和二氟亚甲基类似物。通过双膦酸与适当的5'- O-甲苯磺酰基脱氧核苷之间的反应得到2'-脱氧核苷5'-二磷酸酯的类似物。随后通过激活dNDP的P-2作为其吗啡酸酯添加γ-磷酸酯,然后与无机磷酸酯反应,或使用一种新颖的常规反应,使用对硝基苄基磷酸吗啡酸酯对5'-二磷酸核苷进行磷酸化。
