Glyco-SAMs by ‘Dual Click’: Thiourea-Bridged Glyco-OEG Azides for Cycloaddition on Surfaces
摘要:
A series of NCS-functionalized sugars were synthesized and used in a thiourea-bridging reaction with aminohexa(ethylene glycol) azide [H2N(EG)(6)N-3], a bifunctional oligo(ethylene glycol) derivative, which can be used as key intermediate for the fabrication of biorepulsive glyco-SAMs by a 'dual click' approach. Glyco-SAMs can serve as defined glycocalyx models for the study of carbohydrate-protein interactions. The copper(I)-catalyzed 1,3-dipolar cycloaddition reaction of the obtained glyco-OEG azides was exemplified, which can be used to modify preformed monolayers 'on SAM'.
