A novel method for peptide bond formation utilizing amino acid 2-formyl-4-nitrophenylthio ester has been developed. The reaction can be performed in water-containing media and is compatible with various types of amino acid side-chain functional groups. Use of N-methylmaleinimide as an additive is essential for the reaction to proceed with high efficiency. It captures liberated formyl-substituted thiophenol
已经开发出一种利用氨基酸2-甲酰基-4-硝基苯硫基酯形成肽键的新方法。该反应可以在含水介质中进行并且与各种类型的氨基酸侧链官能团相容。使用N-甲基马来酰亚胺作为添加剂对于反应以高效率进行是必不可少的。它通过1,4-加成,然后醛醇环化,捕获释放的甲酰基取代的苯硫酚。
