抄録

2, 6-Bis-methylthio-and 2, 6-bis-benzylthio-9-(2', 3', 5'-tri-O-benzoyl)-β-D-ribofuranosylpurines were synthesized by the condensation of chloromercury salt of 2, 6-bisalkylthiopurines with 2, 3, 5-tri-O-benzoyl-D-ribofuranosyl chloride. The transformation to 6-dimethylamino-and 6-methylamino-9-β-D-ribofuranosylpurine by the successive amination and desulfurization was achieved.
