The N-nitroso function is introduced as a protecting group for secondary amino acids, and its application in the synthesis of depsipeptides -particularly of Enniatin A -is described. The method proved, however, not to be generally applicable in the synthesis of N-alkylated peptides because of partial racemisation and frequent side reactions.
引入N-亚硝基官能团作为仲氨基酸的保护基,并描述了其在二肽(特别是Enniatin A)的合成中的应用。然而,由于部分外消旋作用和频繁的副反应,该方法证明不适用于N-烷基化肽的合成。
