A three-componentreaction for the synthesis of substituted anilines by a gold(I)-catalyzed domino reaction was developed. Cationic gold catalysts selectively and sequentially activated two different alkynes, which were involved in pyrrole synthesis and subsequent Diels–Alder reaction. The sequential formal (3 + 2) annulation/Diels–Alder reaction of three components provided a variety of substituted

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
