Received Date: 26 July 1995

2-Amino-5-thio-1,3,4-thiadiazoline and 1-O-acetyl-2,3,5-tri-O-benzoylribofuranose were allowed to react by fusion or by the Vorbrüggen procedure.Two products were isolated and characterized to be positional isomers 4-(β-D-ribofuranosyl)-2-amino-5-thio-1,3,4-thiadiazoline and 3-(β-D-ribofuranosyl)-2-imino-5-thio-1,2,4-thiadiazoline by ¹H,¹³C NMR,mass spectra as well as crystallographic analysis.
