The 1 H‐ and 13 C‐NMR data of the dimeric anhydride 1 of 2,3‐ O ‐isopropylidene‐β‐ D ‐ribofuranose are reported together with the 1 H‐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].
