acid chlorides to give amides is disclosed. Reactions are carried out in the presence of silver acetate in non-aqueous environments under heterogeneous phase conditions. Amides are easily recovered in very good to excellent yields and without racemization. The approach is successful in forming peptide bonds starting from N-(4-nitrobenzenesulfonyl)-amino acid chlorides and allows the formation of dipeptides
公开了一种温和的方法用于羧酰氯的氨解以产生酰胺。反应在乙酸银存在下在非水环境中在非均相条件下进行。酰胺很容易以非常高的收率回收,而且没有外消旋作用。该方法成功地形成了从N-(4-硝基苯磺酰基)-氨基酸氯化物开始的肽键,并且当使用N-甲基化的氨基酸衍生物时也允许形成二肽。
