characterized and tested for reactivity in solution peptide synthesis. The new triazinyloxyimino derivatives failed to activate the carboxyl group during formation of peptide bonds, but gave the corresponding N-triazinyl amino acid derivatives as a major product. The oxyma (ethyl 2-cyano-2-(hydroxyimino)acetate) uronium salt was superior to other uronium salts in terms of racemization, while 2-chloro-4
一类新的 1,3,5-triazinyloxyimino 衍生物被制备、表征和测试在溶液肽合成中的反应性。新的三嗪基氧基亚氨基衍生物在肽键形成过程中未能激活羧基,但产生了相应的 N-三嗪基氨基酸衍生物作为主要产物。oxyma(2-氰基-2-(羟基亚氨基)乙酸乙酯)脲盐在外消旋化方面优于其他脲盐,而 2-氯-4,6-二甲氧基-1,3,5-三嗪(CDMT,9 ) 给出了最好的结果。
