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

Deprotected iminosugar alkenes were subjected to thiol–ene coupling with deprotected sugar thiols to afford new imino-disaccharides. Two thiol–ene couplings converted these alkenes into iminosugar thiols and then multivalent iminosugars.

Novel biologically important mono- and bicyclic iminosugars have been synthesized from commercially available sugars following high yielding and short synthetic sequences. These unnatural N-heterocycles have been further tested against several glycosidases and some of them showed good inhibition of the enzymes with moderate selectivity.
