metal salts and quaternary ammonium salt to these reactions. It is worth mentioning that the yield of aliphatic compound 2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl butyrate (3l) was highly improved when using C6mim·OTf as solvent compared with the normal volatile solvents under the same catalysts. This green approach has been proved to be practical and compatible with a wide range from aliphatic to aromatic

Oligosaccharides are involved in numerous biological processes. Achieving optimal anomeric selectivity and regioselectivity remains challenging. Herein, we present a method for the oxidative glycosylation of thioglycosides with hypervalent iodine reagents derived from carboxylic acid to form C–O bonds. The reaction of thioglycosides with various hypervalent iodine carboxylates afforded acyl O-glycosyl
