The synthesis of peptides containing multiple Aib residues was accomplished using Fmoc-Aib-Cl in presence of KOBt. As no additional base was added, the duration of coupling reactions could be extended. Thus, the synthesis of the alamethicin 1–4 fragment, Aib-Pro-Aib-Ala, the emerimicin 2–6 fragment, Aib-Aib-Aib-Val-Gly and the Aib tetramer, Fmoc-(Aib)4-OBzl were accomplished in good yield and purity
在KOBt存在下,使用Fmoc-Aib-Cl完成包含多个Aib残基的肽的合成。由于不添加额外的碱,可以延长偶联反应的持续时间。因此,合成了乐果霉素1-4片段,Aib-Pro-Aib-Ala,Emerimicin 2-6片段,Aib-Aib-Aib-Val-Gly和Aib四聚体,Fmoc-(Aib)4 -OBzl。以高收率和纯度完成。
