  Nucleosides and Nucleotides. 140. Synthesis and Antileukemic Activity of 5-Carbon-Substituted 1-β-d-Ribofuflranosylimidazole-4-Carboxamides

  摘要：

  Synthesis of 5-carbon-substituted 1-beta-D-ribofuranosylimidazole-4-carboxamides are described. Treatment of 5-iodo derivative 8 with methyl acrylate in the presence of palladium catalyst gave (E)-5-(2-carbomethoxyvinyl)-1-(2,3,5-tri-O-acetyl- beta-D-ribofuranosyl)imidazole-4-carboxamide (9), followed by appropriate manipulations to afford various 5-carbon-substituted imidazole derivatives 1-7. The antileukemic activities of these imidazole nucleosides are also described.
