systems. Here, we carried out the peptide bond formation reaction in one of the environmentally secure solvents, ‘ionic liquids’ in the presence of coupling reagent and in the absence of external base at room temperature, affording dipeptides in good to excellent yields.

摘要 近年来,由于绿色溶剂介质和催化系统的生态性能,合成有机化学中绿色方法的发展引起了人们的关注。在这里,我们在室温下在一种环境安全的溶剂(“离子液体”)中在偶联剂存在下且在不存在外部碱的情况下进行了肽键形成反应,从而以良好的产率获得了优异的二肽。 图形概要概述我们在室温下,在不存在外部碱的情况下,在偶合试剂存在下,在离子液体中进行肽键形成反应,从而以良好或极好的收率得到二肽。
