[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, Fmoc-MeVal-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
[2 S,3 S -Hmp] -Aureobasidin L 2通过溶液和固相肽合成相结合已成功合成。在溶液相中制备了所有的受Fmoc保护的残基,包括二肽,Fmoc-MeVal-Hmp-OH。使用选定的
偶联剂,包括
HBTU /
HOBt,
HATU / HOAt和
BTC /
可力丁,在
氯三苯甲基
树脂上进行链延长。切割线性地二壬肽后,环化,得到所需的环二肽。
