Deprotection regioselective de D-glycals chloroacetyles par l'acetate d'hydrazine
摘要:
Chloroacetates are susceptible to regioselective deprotection by hydrazine acetate, and provide an interesting tool for the synthesis of monomers suitably tailored for the preparation of complex oligosaccharides.

Novel analogs of fusidic acid are described with one or more carbohydrate units attached. Certain glycosylated analogs of fusidic acid have enhanced solubility properties in diluents or excipient of choice as compared to unmodified fusidic acid. Certain glycosylated analogs may be employed as chemotherapeutic agents and particular analogs may be useful for fighting anti-microbial infections.

The homogeneous azidophenylselenylation of diversely protected mono-, di- and trisaccharide glucals was studied to evaluate the influence of protective groups, N-3 and I donors, temperature and solvent on the stereoselectivity of the formation of corresponding phenyl 2-azido-2-deoxy-1-seleno-alpha-D-gluco- and -manno-adducts.
