Pyrazolo[4,3-d]pyrimidine nucleosides. Synthesis and antiviral activity of 1-β-D-ribofuranosyl-3-methyl-6-substituted-7 H-pyrazolo[4,3-d]pyrimidin-7-ones

N1 analogues of formycin B, with substituents at the 3 and 6 positions of the pyrazolo[4,3-d]pyrimidine moiety were synthesized by the direct SnCl4-catalyzed ribosylation method. The site of the glycosidic linkage and the anomeric co
