A simple, broadly applicable protocol for amidation and esterification reactions is described. Thereby, 4-acetamidophenyl triflimide (AITF), a crystalline stable reagent, is employed for the activation of carboxylic acids. The use of AITF as a coupling agent is demonstrated in the synthesis of peptides, amides and esters under mild conditions in good to excellent yields. Notably, peptide segment condensations
描述了一种简单、广泛适用的酰胺化和酯化反应方案。因此,结晶稳定试剂 4-乙酰氨基苯基三氟甲酰亚胺 (AITF) 可用于活化羧酸。 AITF 作为偶联剂的使用在温和条件下的肽、酰胺和酯的合成中得到了证明,产率良好至优异。值得注意的是,还完成了肽片段缩合。完成了多种合成方案,展示了广泛的底物范围和良好的官能团兼容性。在此,我们系统地总结了AITF在肽合成策略中的应用。
