Abstract: | The 1H- and 13C-NMR data of the dimeric anhydride 1 of 2,3-O-isopropylidene-β-D -ribofuranose are reported together with the 1H-NOE values. The data show that the products of the polymerization of 1,5-anhydro-2,3-O-isopropylidene-β-D -ribofuranose are α- and β-D -ribofuranans and not an α-D -ribofuranan and a β-D -ribofuranan and a β D ribo-pyranan as claimed before 2] 3]. |
