[2S,3S-Hmp]-Aureobasidin L 2 has been successfully synthesised through a combination of solution- and solid-phase peptide synthesis. All of the Fmoc-protected residues including a depsidipeptide, FmocMeVal-Hmp-OH, were prepared in solution phase. Chain elongation on chlorotrityl resin was undertaken using selected coupling reagents including HBTU/HOBt, HATU/HOAt and BTC/collidine. Cleavage of the linear depsinonapeptide was followed by cyclisation to give the desired cyclodepsipeptide.
