摘要

以2,6-双三唑嘌呤阿拉伯核苷为原料,通过C(6)-区域选择性亲核取代1,2,3-三唑基与吡咯烷基,得到C(6)-吡咯烷基衍生物。用核磁共振、x射线、紫外可见光谱和发射光谱对所得化合物进行了研究。核磁共振和x射线研究明确证实了所得化合物的阿拉伯糖残基的吡喃糖形式和α-构型。

The Synthesis and X-ray Studies of 6-pyrrolidinyl-2-triazolyl Purine Arabinonucleoside
C(6)-Pyrrolidinyl derivative with triazolyl moiety at C(2)-position was obtained from 2,6-bis-triazolylpurine arabinonucleoside via C(6)-regioselective nucleophilic substituon of 1,2,3-triazolyl moiety with pyrrolidine. The obtained compound was studied by NMR, X-ray, UV/VIS and emission spectra. Pyranose form of arabinose residue and α-configuration of the obtained compound were unambiguously proven by NMR and X-ray studies.
