9-(2-Deoxy-β-D-erythro-pentofuranosyl)-6-(4-substituted phenyl)purines, 9-(5-deoxy-β-D-ribofuranosyl)-6-(4-substituted phenyl)purines and 9-(2,3-dihydroxypropyl)-6-(4-substituted phenyl)purines were prepared by the Suzuki-Miyaura cross-coupling reactions of the corresponding protected 9-substituted 6-chloropurines with substituted phenylboronic acids followed by MeONa mediated deprotection. In contrast to the highly active 6-phenylpurine ribonucleosides, the title compounds did not show any considerable cytostatic activity.
使用相应的保护基保护的9-取代的6-氯嘌呤与取代的苯基硼酸经Suzuki-Miyaura交叉偶联反应后,再经MeONa介导的脱保护反应,制备了9-(2-去氧-β-D-<斜体>赤霉素斜体>-戊呋糖基)-6-(4-取代苯基)嘌呤、9-(5-去氧-β-D-核糖基)-6-(4-取代苯基)嘌呤和9-(2,3-二羟丙基)-6-(4-取代苯基)嘌呤。与高度活性的6-苯基嘌呤核苷酸不同,这些化合物没有显示出任何显著的细胞毒素活性。
