  Synthesis of 6-Substituted Purine N⁷-(2-Deoxy-β-D-Ribonucleosides) via Anion Glycosylation and Anomerization During the N⁷/N⁹-Glycosyl Transfer

  摘要：

  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.
