Stereospecific access to β-mannosides from glucose-derived 1,2-orthoesters as glycosyl donors

A new, stereospecific synthesis of β-mannosides from glucose-derived 1,2-orthoesters has been developed by a simple four step procedure, comprising β-specific glycosidation of the 1,2-orthoesters, 2′-O-deacetylation, 2′-O-triflation, and SN 2 type inversi
