the synthesis and utility of ethyl 2-(tert-butoxycarbonyloxyimino)-2-cyanoacetate (Boc-Oxyma) as an efficient coupling reagent for racemization-free esterification, thioesterification, amidation reactions and peptide synthesis that uses equimolar amounts of acids and alcohols, thiols, amines or amino acids, respectively. Its application to solid phase as well as solution phase peptide synthesis is also
在这里,我们报告2-(叔丁氧基羰基氧基亚氨基)-2-氰基乙酸乙酯(Boc-Oxyma)的合成和实用性,该化合物是用于等消旋酯化,硫代酯化,酰胺化反应和使用等摩尔量的酸和分别是醇,硫醇,胺或氨基酸。还证明了其在固相以及溶液相肽合成中的应用,并讨论了机理研究。就其高反应性和作用机理而言,Boc-氧化酶类似于众所周知的偶联剂COMU 1- [1-氰基-2-乙氧基-2-氧代亚乙基亚氨基氧基)-二甲基氨基吗啉代]六氟磷酸uro}。但是,它不仅易于制备,而且易于回收和再利用,从而产生的化学废物少得多。
