Abstract
Orthoester-linked d-arabinofuranose oligosaccharides were isolated in high yield for the first time via glycosylations with 2-O-chloroacetyl-substituded d-arabinofuranose thioglycosides promoted by NIS–AgOTf in the presence of 4 Å molecular sieves in CH2Cl2. These orthoesters can be rearranged into the isomeric glycosidically-linked oligosaccharides by treatment with TMSOTf in CH2Cl2, or in situ by extension of the reaction time.
