Stereomeric Pyrrolidinopentoses Bearing an Imidazole Ring − Synthesis, Chiroptical Properties, and Evaluation as Potential Sugar-Mimic Glycosidase Inhibitors
C(4)-metallated imidazole derivatives to the appropriately configured and protected aldotetroses. Cyclisation of the resulting linear imidazolo-carbohydrates was performed by means of intramolecular Walden inversion processes, followed by deprotection to afford the five target imidazolo-sugars. Three of the four D-configured stereomers proved to be good to moderate glycosidaseinhibitors, as determined
