A library of dimers and heterodimers of both enantiomers of 2-O-alkylated iminoxylitol derivatives has been synthesised and evaluated on β-glucocerebrosidase (GCase), the enzyme responsible for Gaucher disease (GD). Although the objective was to target simultaneously the active site and a secondary binding site of the glucosidase, the (−)-2-iminoxylitol moiety seemed detrimental for imiglucerase inhibition

have addressed the application of sulfonium salts to the modification of biomolecules such as nucleic acids and proteins. Since these large biomolecules play important roles in biological processes, a convenient and fast method for their modification is greatly needed. In this work, for the first time, we used a tandem method of sulfonium alkylation and click chemistry (CuAAC) for modification of biomolecules

Diamides containing alkyne and azido were self-assembled into nanotubes and were reacted under their self-assembled state with small molecules by “click chemistry”; the resulting compounds remain self-assembled into new nanotubes that cannot be formed by simple self-assembly of the constituting molecules.

Nucleophilic transformations of azido-containing carbonylcompounds are discussed. The phosphazide formation from azides and di(tert-butyl)(4-(dimethylamino)phenyl)phosphine (Amphos) enabled transformations of carbonylgroups with nucleophiles such as lithium aluminum hydride and organometallic reagents. The good stability of the phosphazide moiety allowed us to perform consecutive transformations
