A simplified method for the synthesis of activated esters of N-protected amino-acids is described. The synthesis proceeds through the aminolysis of various active esters of t-butyl or benzyl carbonate, and the leaving group displaced in this process becomes reincorporated by the additon of dicyclohexylcarbodi-imide to the reaction mixture, to give the desired compound.
描述了一种用于合成N-保护的氨基酸的活化酯的简化方法。合成通过碳酸叔丁酯或碳酸苄酯的各种活性酯的氨解进行,并且在该过程中置换的离去基团通过将二环己基碳二亚胺添加到反应混合物中而重新结合,从而得到所需化合物。
