method for the synthesis of dipeptides has been developed, which does not require any coupling reagents. This method is based on the reaction of readily available HCl salts of amino acid methyl esters with tetrabutylphosphonium amino acid ionic liquids. The isolation procedure of stepwise treatment with AcOH is easy to carry out. The method was extended to the synthesis of tripeptide, tyrosyl‐glycyl‐glycine
已经开发了合成二肽的通用方法,该方法不需要任何偶联剂。该方法基于容易获得的氨基酸甲酯的HCl盐与四丁基phosph氨基酸离子液体的反应。用AcOH逐步处理的分离过程很容易进行。该方法还扩展到IMREG-1中也存在的三肽酪氨酰甘氨酰甘氨酸的合成。
