We demonstrate N-phosphorylation and N-thiophosphorylation of unprotected aminonucleosides in aqueous media. N-Phosphorylations using phosphoric chloride and N-thiophosphorylations using thiophosphoryl chloride were explored as functions of pH using 5′-amino-5′-deoxyguanosine as substrate. These reagents were compared to phosphodichloridate and thiophosphodichloridate ions, and the methodology was applied to other aminonucleosides. S-Alkylations of the nucleoside N-thiophosphoramidates were investigated as functions of pH and alkylating agent.
我们在水介质中证明了无保护氨基核苷的N-磷酸化和N-硫磷酸化。以5'-氨基-5'-脱氧鸟苷为底物,探索了使用磷酰氯进行N-磷酸化和使用硫磷酰氯进行N-硫磷酸化作为pH值的函数。将这些试剂与磷二氯酸酯和硫磷二氯酸酯离子进行了比较,并将该方法应用于其他氨基核苷。以pH值和烷基化剂为函数,研究了核苷N-硫磷酰胺的S-烷基化。
