Abstract
Solid phase synthetic methods of forming sulfur-linked disaccharides and oligosaccharides are described, wherein a saccharide or oligosaccharide bearing a protected thiol-group at the anomeric carbon is immobilized onto a solid support at any position other than the anomeric carbon atom of the reducing sugar. The resultant immobilized thiol, or a derivative thereof, undergoes nuclcophilic saccharide addition to provide a di- or oligosaccharide.
