A new glycosylation strategy that allows chemoselective activation of the S-thiazolyl (STaz) moiety of a glycosyl donor over the temporarily deactivated glycosyl acceptor, bearing the same anomeric group, has been developed. This deactivation is achieved by engaging of the STaz moiety of the glycosyl acceptor into a stable palladium(II) complex. Therefore, obtained disaccharides are then released from the complex by simple ligand exchange. [reaction: see text]
