The 1,3-dipolar cycloadditionreaction of 3′-O-propargyl guanosine with various in-situ generated nitrileoxides in the presence of DMF as a solvent is described. It is noteworthy that the reaction is highly regioselective that affords biologically important guanosine containing isoxazole moiety in good yields with high purities.

example of the synthesis of new dinucleotide cap analogcontaining propargyl group such as m7,3′-O-propargylG[5′]ppp[5′]G is reported. The effect of propargyl cap analog with standard cap was evaluated with respect to their capping efficiency, in vitro T7 RNA polymerase transcription efficiency, and translation activity using cultured HeLa cells. It is noteworthy that propargyl cap analog outperforms

First chemical synthesis of 3′-O-1,2,3-triazolyl-guanosine-5′-O-monophosphate by copper catalyzed click chemistry is described. The present cycloaddition reaction involves, in situ generation of azide from the corresponding bromide followed by copper catalyst cycloaddition with 3′-O-propargyl guanosine monophosphate in water, in the presence of catalytic amount of β-cyclodextrin. The CuAAC reaction
描述了通过铜催化的点击化学的3' - O -1,2,3-三唑基-鸟苷-5'- O-单磷酸的第一化学合成。本发明的环加成反应包括在催化量的β-环糊精存在下,从相应的溴化物中原位生成叠氮化物,然后在水中将铜催化剂与3'- O-炔丙基鸟苷单磷酸环加成环。CuAAC反应是高度区域选择性的,形成具有良好产率和高纯度的1,4-环加合物。最终化合物3'-O -三唑取代的鸟嘌呤单磷酸鸟苷有潜力用于各种生物分子,例如标记的核酸,mRNA二核苷酸帽类似物,用于分子生物学及其在治疗领域中的应用。
