The synthesis of a small library of (pyrrolidin-2-yl)triazoles via copper catalysed cycloaddition of an alkynyl iminocyclopentitol and a set of commercial and synthetic azides has been achieved. The in situscreening for the activity towards alpha-fucosidase of the resulting triazoles has allowed the identification of one of the most potent and selective pyrrolidine derived inhibitors of this enzyme

libraries (1a-l, 1a'-l' and 2a-l) of dimeric iminosugars through CuAAC reaction between three different alkynyl pyrrolidines and a set of diazides was carried out. The resulting crude dimers were screened in situ against two α-fucosidases (libraries 1a-l and 1a'-l') and one β-galactosidase (2a-l). This method is pioneer in the search of divalent glycosidase inhibitors. It has allowed the rapid identification

The hydrophobic landscape in fucosidase was studied with the aid of iminosugar derivatives featuring phenyl substituents in variable orientations with respect to the iminocyclitol core, and at various distances from it, to explore the key binding interactions that stabilise the enzyme–inhibitor complex.
