Amphiphilk carbohydrates as a tool for molecular recognition in organized systems, vesicles can be formed. The recognition, by specific receptors, of carbohydrates assembled as monolayers or Langmuir-Blodgett films, can display quantitative information such as the thermodynamic parameters of binding or cluster effects, whereas the recognition at the surface of vesicles mainly aff

Nucleophilic C-glycosyl donors for C-glycoside synthesis,vity at C(1) (the anomeric site). A wide variety of “anionic” (organometallic derivatives) and neutral (free radical) C(1) nucleophiles are known and examples of all structural types are presented. Coverage includes methods for generating effective C(1)-nucleophiles, their reactivity and utility in

Synthesis of C-glycosides of biological interest,analogs in which a carbon atom substitutes the oxygen involved in the glycosidic linkage. This modification compromises the anomeric reactivity of the sugar, giving rise to antimetabolites that can inhibit carbohydrate processing enzymes. The synthesis of C-glycosides can be performed from natural s

Chemical and chemo-enzymatic approaches to glycosidase inhibitors with basic nitrogen in the sugar racted considerable interest in the recent past. Low molecular weight glycosidase inhibitors are structurally frequently related to the natural substrates or, more importantly, to the oxocarbonium ion like transition state of glycoside hydrolysis. Sugar shaped inhibitors with a basic nitrogen instea
