A simple method for the synthesis of a sugarfuranoid trans vicinal diacid and its incorporation into the N-terminal tetrapeptide sequence (H-Phe-Trp-Lys-Thr-OH) to get glycopeptide 8 has been described. 2D NMR and MD simulation studies of 8 clearly show that the sugardiacid adopts a γ-turn conformation towards the N-terminus.
