    • 6 starting from HMPB-tentagel resin esterified with Fmoc-Glu(tBu). Peptides 9 and 10 were obtained after cleavage with reagent K (2h). Yields of crude peptides 9 and 10 were 77% and 82%, respectively, based on the initial substitution of the resin. Cleavage with 80% acetic acid at 80 degrees for 1h afforded crude peptide 11 in 60 % yield.

    • The peptides were characterized by analytical HPLC (Merck RP-18, 5μm, 4 × 125 mm, Lichrospher-100Å) using an acetonitril gradient (0–80% acetonitril in 30 min, flow: 1ml/min) and UV detection at 230 nm.

    • Poros HPLC was carried out on a Poros II R/H colum (100× 4.6 mm) running a gradient from 10% B to 100% B in 10 min (A: 0.1 % TFA, B: 80% acetonitril / 20% water; flow rate: 4ml/min; UV detection: 230 nm). The partially protected peptide 11 was obtained in 16% yield, with respect to the crude material.
