“…Synthesis of peptides Boc-N-MeAla-8-Ala-OMe (7). The coupling reactions were performed with both reagents: DCC/HOBt (46), BOP-Cl (25,26), Piv-CI (20). DCC/HOBt method: A solution of P-AlaOMe,HCI (30mmo1, 4.19g), and DIEA (30mmo1, 5.20 mL) in 30 mL CHzClz was stirred at 0 C. Then Boc-N-MeAla (30 mmol, 6.09 g), HOBt (30 mmol, 4.05 g) and DCC (33 mmol, 6.80 g) were added and stirred for 1 h at 0°C under a nitrogen atmosphere.…”

A general strategy for the synthesis of destruxin analogues is described and applied to a particular example, D-Lac-6 destruxin E. The tetrapeptide Boc-Ile-N-MeVal-N-MeAla-~-Ala-OMe (2) was chosen as the basic starting compound, and its preparation was optimized. This fragment was then coupled with the compound (D)Lac-Pro, and the resulting peptide was cyclized by the DEPC or DPPA/HOBt/DMAP methods at 21 and 30% yield, respectively. The biological activity of the analogue obtained was established by injection to an insect host.
