Reaction of 4-amino-3-aryl-1,2,4-triazol-5-thiols with 2,3,4,5,6-penta
-O-acetyl-D-gluconic acid or 2,3,4,5-tetra-O-acetylgalactaric acid in
the presence of phosphoryl chloride gave the corresponding -yl)-3-aryl
-1,2,4-triazolo[3,4-b]1,3,4-thiadiazole or 3-aryl-1,2,4-triazolo[3,4-b
]1,3,4-thiadiazol-6-yl) galacto-tetritols, respectively which upon de-
O-acetylation with methanolic ammonia or sodium ethoxide in ethanol ga
ve the corresponding acyclo C-nucleosides.
