Twelve new 1 H-pyrazolo[3,4-b]pyridine phosphoramidate derivatives were synthesized under mild conditions by nucleophilic aromatic substitution reaction of aminoalkylphosphoramidates over 4-Cl substituted pyrazolo[3,4-b]pyridine in good yields. The new compounds were characterized by IR, 1 H, 13 C and 31 P NMR spectroscopy and HRMS. The crystal structure of one compound was solved by X-ray diffraction
十二个新的 1 H-吡唑并 [3,4-b] 吡啶氨基磷酸酯衍生物在温和条件下通过氨基烷基氨基磷酸酯在 4-Cl 取代的吡唑并 [3,4-b] 吡啶上的亲核芳香取代反应以良好的产率合成。新化合物通过红外、 1 H、 13 C 和 31 P NMR 光谱和 HRMS 进行了表征。一种化合物的晶体结构通过 X 射线衍射解析,并显示出涉及氨基磷酸酯基团的分子间相互作用网络。
