International audience; Well-defined glyco-polyorganosiloxanes were synthesized by the Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition reaction (often simply referred to as click chemistry). N-propargylglycosylamines 2 and 4 were first synthesized from cellobiose (1) and xylogluco-oligosaccharide XGOs 3 without protecting groups. The azide function was introduced into polydimethylsiloxanes [PDMS: 5 (MDM) and 7 (MDM)] by azidolysis of the counterpart epoxy silicon with NaN3 to afford the mono-azido 6 and di-azido 8 derivatives, respectively. The coupling reaction took place in a hydro-alcoholic medium in the presence of CuSO4/sodium ascorbate as catalyst. Only one compound, MDM-click-XGO 12 showed good solubility in water with interesting surfactant properties.
