We present here the stereoselective synthesis of a series of 2/3-N-pyrrolidine derivatives of glycosides produced by diastereoselective double reductive amination ringclosure of 1,4-dicarbonyl compounds. These precursors were produced by tandem ozonolysis–reduction or Wacker oxidation of known alkenes. The potential of these new compounds as glycosidase inhibitors is illustrated for compound 16, showing
