The synthesis of a chitobiosylated peptide thioester by the <I>t</I>-butoxycarbonyl (Boc) strategy is demonstrated. Boc-Asn carrying benzyl-protected chitobiose was introduced during application of the Boc mode solid-phase method. HF treatment of the resulting protected peptide resin gave the desired chitobiosylated peptide thioester. This thioester was used to prepare the peptide sequence derived from extracellular matrix metalloproteinase inducers (emmprin) (34-94), (34-118) and (22-118) by the thioester segment condensation method. The conformation of these glycopeptides is characterized by circular dichroism (CD) spectral measurement.
