  摘要：

  已经在不同浓度的氧离子下测量了几种6-取代的9-（2-脱氧-β-D-赤-戊呋喃糖基）嘌呤和9-（1-烷氧基乙基）嘌呤的水解速率常数。解释了改变烷氧基极性性质对未取代的9-（1-烷氧基乙基）嘌呤水解的影响，这表明该反应是通过质子化碱部分的限速离去并伴随形成一个烷氧基乙基氧碳鎓离子。通过比较6-取代基对这些化合物及其9-（1-烷氧基乙基）反应剂的反应性的影响，将相同的机理应用于9-（2-脱氧-β-D-赤-戊呋喃糖基）嘌呤的水解。 -部分。当2'-脱氧腺苷水解后进行1 H NMR光谱。

• Purine nucleoside synthesis from uridine using immobilised Enterobacter gergoviae CECT 875 whole cells

  Biocatalysed purine nucleoside synthesis was carried out using immobilised Enterobacter gergoviae CECT 875. Similar yields (80-95%) in adenosine were obtained with both free and immobilised cells though in the last case a long reaction time was necessary. The immobilised cells can be reused at least for more than 30 times without significant loss of enzymatic activity. The immobilised biocatalyst in agarose is active in the synthesis of unnatural nucleosides. (C) 2003 Elsevier Science Ltd. All rights reserved.
• Synthesis of 6-Substituted Purine N⁷-(2-Deoxy-β-D-Ribonucleosides) via Anion Glycosylation and Anomerization During the N⁷/N⁹-Glycosyl Transfer

  The synthesis of the 7-(2-deoxy-beta-D-erythro-pentofuranosyl) adenine (Ib) as well as the corresponding hypoxanthine- and purine nucleosides 3 and 4 is described employing the stereoselective nucleobase anion glycosylation. The N-7/N-9- isomer distribution of the 6-substituted purine (2-deoxyribonucleosides) depends on 6-substituent. Glycosyl transfer of 8a resulted in anomerization and yielded a mixture of the anomeric 6-methoxypurine N-9-(2-deoxy-D-ribonucleosides) 7a/7d. The preferred glycosylic bond conformation of purine N-7-(2-deoxyribonucleosides) is anti.
