Syntheses of alkenylated carbohydrate derivatives toward the preparation of monolayers on silicon surfaces
摘要:
This note describes the synthesis of different alkenylated carbohydrate derivatives suitable for direct attachment to hydrogen-terminated silicon surfaces. The derivatives were alkenylated at the C-1 position, while the remaining hydroxyl groups were protected. The development of such new carbohydrate-based sensing elements opens the access to new classes of biosensors. (C) 2004 Elsevier Ltd. All rights reserved.

We develop herein the synthesis of a new class of monocatenary and bolaform surfactants from d-glucose, d-galactose and lactose. Two main pathways have been investigated: microwave-assisted glycosylation followed by olefincross-metathesis, and the one-step click-chemistry methodology. Tensioactive properties of these new compounds have been studied in order to characterize the physicochemical behaviour
