known that sugars extend the biological half-life of these molecules. Furthermore, the attachment of a sugar residue to a peptide sequence could improve the affinity of the molecule for its receptor. For this reason, several glycosylated enkephalins have been synthesisedlm3. Chemical syntheses of glycopeptides are well developed”. However, because carbohydrates contain multiple hydroxylgroups of similar
