coupling reagent, ethyl 1-hydroxy-1H-1,2,3-triazole-4-carboxylate (HOCt), has been designed and synthesised for application to solid phase peptide synthesis using Fmoc chemistry. It is used in combination with carbodiimide reagents, has very high coupling efficiency, and does not absorb at 302nm, thus allowing real-time monitoring of each coupling cycle. Its applications in the synthesis of endothelin
已经设计并合成了一种最佳的偶联剂,1-羟基-1H-1,2,3-三唑-4-羧酸乙酯(HOCt),可用于使用Fmoc化学的固相肽合成中。它与碳二亚胺试剂结合使用,具有很高的偶联效率,并且在302nm处不吸收,因此可以实时监控每个偶联循环。还讨论了其在合成内皮素类似物和困难序列中的应用。
