Abstract We report the tandem Staudinger/aza-Wittig/Ugi three-component reaction mediated synthesis of a 64-member compound library of aza-C-glycosides. The library is composed of four pyrrolidine and three piperidine scaffolds, onto which a number of functional groups is grafted to form seven sublibraries. Variation in the library is achieved by transformation of two pentoses and a hexose into the corresponding 4-azidopentanal and 5-azidohexanal derivatives as precursors for the Staudinger/aza-Wittig process. Further variation is achieved by using different isocyanides as well as protective- and functional-group manipulations on the fully protected Ugi-3CR intermediates. Preliminary biological evaluation of the compound library revealed several low micromolar inhibitors of human acid glucosylceramidase
