A glycosylated fragment of the bovine glycoprotein ribonuclease B (1) was synthesized corresponding to amino acids 21-25 with a complex type biantennary N-glycan linked to Asn(24). The total synthesis of the undecasaccharide-glycopentapeptide 1 was accomplished by modem solution phase glycopeptide chemistry combined with enzymatic techniques for the removal of protective groups and a regio- and stereoselective transfer of the terminal carbohydrates using glycosyltransferases.
