    • To evaluate the efficacy of the macrocyclization at different locations, we also attempted the cyclization of peptide I by linking the Tyr-3 and Ala-4 residues in DMF by using the reagents A-D of Table 1. Reagents A, B, and D did not afford cyclized products, whereas reagent C [HBTU (4 equiv), HOBt (4 equiv), and DMAP (8 equiv)] gave 1 in 13% yield. By the same method, peptide II afforded 6 in 17% yield. The results indicated that cyclization at this position is feasible, but we did not consider that this strategy is more advantageous over the scheme described in the text.
