The structure–activity relationship of lipophilicaza-C-glycosides as inhibitors of the three enzymes of glucosylceramidemetabolism is investigated. A library of β-aza-C-glycosides was synthesized with variations in N-alkylation and the linker length/type to the lipophilic moiety. A cross-metathesis reaction was used to prepare a second library of α-aza-C-glycosides with D-gluco, L-ido and D-xylo

Multifarious sugar lactols were efficiently transformed into the corresponding phenolic glycosides by treating with aryl bromides in acetonitrile with Ir[dF(CF3)ppy]2(dtbbpy)(PF6) as a photocatalyst under visible light irradiation. Both pyranoses and furanoses or even disaccharide could all suffer this glycosylation protocol under mild reaction conditions. A variety of phenyl glycosides can be produced
A simple and highly regioselective hydrogenolysis of the anomeric benzyl group is reported. The generality and the scope of the reaction were evaluated by applying it to a number of diversly protected benzyl monosaccharides and disaccharides that lead to the formation of the corresponding hemiacetals in good yield.
