A number of activated esters of amino acid and peptide derivatives were reacted with various organic amines, including amino acid esters. The good yields obtained, and the mild reaction conditions make it seem possible that the activated ester method of acylation may be of good use in peptide synthesis. Aminolysis by aromatic amines and by secondary amines proceeds only slowly, but the reaction can
使许多氨基酸和肽衍生物的活化酯与各种有机胺,包括氨基酸酯反应。获得的良好收率和温和的反应条件使得活化的酯化酰化方法似乎可以在肽合成中很好地使用。芳香胺和仲胺的氨解仅缓慢进行,但是通过强叔胺和酸的催化作用可大大促进该反应。
