We discovered that the hypervalent iodine(III) reagent could mediate the glycosylation reaction by activating the thio-glycoside donors which were prepared from glycosyl 1-O-acetate and odorless p-octyloxybenzenethiol.  By using this method, trisaccharides as well as disaccharides could be easily synthesized under mild reaction conditions. All the chemicals employed in this method are enviromentally-benign.
