Synthesis of the repeating trisaccharide unit of the cell wall lipopolysaccharide of Escherichia coli type 8

Efficient one-pot per-O-acetylation–thioglycosidation of native sugars, 4,6-O-arylidenation and one-pot 4,6-O-benzylidenation–acetylation of S-/O-glycosides catalyzed by Mg(OTf)2

Sequential one-pot per-O-acetylation–S-/O-glycosidation under neat condition, regioselective 4,6-O-arylidenation and sequential one-pot benzylidenation–acetylation of Mg(OTf)₂as non-hygroscopic, recyclable catalyst are reported.

Expeditious synthesis of the tetrasaccharide cap domain of the Leishmania donovani lipophosphoglycan using one-pot glycosylation reactions

Expeditious syntheses of the tetrasaccharide cap related to the lipophosphoglycan ofLeishmania donovaniwere achieved by sequential one-pot glycosylation reactions.

Synthetic routes toward the trisaccharide related to the lipopolysaccharide of Burkholderia sp. HKI-402 (B4)

A stepwise and one-pot sequential synthesis of the trisaccharide are reported, using trichloroacetimidate and thioglycosyl donors and a 3-(N-benzyloxycarbonyl) propyl glycoside acceptor.

Efficient activation of thioglycosides with N-(p-methylphenylthio)-ε-caprolactam-TMSOTf

N-(p-Methylphenylthio)-ε-caprolactam (1) in combination with trimethylsilyl trifluoromethanesulfonate (TMSOTf) provides an efficient thiophilic promoter system, capable of activating different thioglycosides. Both 'armed' and 'disarmed' thioglycosyl donors were activated for glycosidic bond formation. Notably, this reagent combination works well in reactivity-based one-pot oligosaccharide assembly strategy.
