✦ Synopsis
The syntheses of the imidazolo-pyrrolidino-pentoses ent-2 (Larabino), 3 (D-xylo), 4 (D-lyxo), ent-4 (L-lyxo), and 5 (D-ribo) are reported, completing the series of all eight possible stereomers. The corresponding five linear imidazolo sugar precursors were prepared by nucleophilic addition of C(4)metallated imidazole derivatives to the appropriately configured and protected aldotetroses. Cyclisation of the resulting
