As the analog of thioinosine, 2-methyl-, 2-ethyl-, 2-methylthio-, and 2-methyiamino-6-mercapto-9-β-D-ribofuranosylpurine were synthesized. From thio-AICA-riboside, 5-formamido-1-(2', 3', 5'-tri-O-formyl-β-D-ribofuranosyl)-4-imidazolethiocarboxamide and 5-acetamido-1-(2', 3', 5'-tri-O-acetyl-β-D-ribofuranosyl)-4-imidazolethiocarboxamide were also prepared.
