  The diverse presence as well as their very specific bio‐responses of glycoconjugates found in all living species requires scientists to synthesize the precise structure of these complex oligosaccharides for various studies on glycoscience.The first and most difficult task is to achieve complete stereocontrol of glycosylation reaction.Theres a plethora of synthetic methodologies which have emerged to solve this formidable challenge.But very few approaches were able to offer the sole α‐ OR β‐glycosylated products,even at the cost of complicating the preparative route or usage of exotic chiral auxiliaries to drive the stereoselectivity.These glaring issues certainly diminished the application to higher and more complex oligosaccharides since each type of anomers required its own custom scaffold to prepare.This talk will highlight our recent progress on new glycosylation methods.Our method enables construction of 1,2‐,1,3‐,1,4‐,and 1,6‐glycosidic linkages in high yields and both isomers can be obtained in high stereoselectivity.
