The 4,4,4-trifluoro-3-oxo-1-butenyl group is proposed as a suitable protecting group for the protection of the N-H terminal of amino acids in peptide synthesis. Amino acids react with 4-ethoxy-1,1,1-trifluoro-3-buten-2-one to give the N-protected amino acids, the protecting group can be removed by acidic hydrolysis. The formation of peptide bonds using on N-4,4,4-trifluoro-3-oxo-1-butenyl protected amino acids occurs without racemization.
提出4,4,4-三氟-3-氧代-1-丁烯基作为在肽合成中保护氨基酸N-H末端的合适保护基团。氨基酸与4-乙氧基-1,1,1-三氟-3-丁烯-2-酮反应生成N-保护的氨基酸,该保护基团可以通过酸性水解去除。使用N-4,4,4-三氟-3-氧代-1-丁烯基保护的氨基酸形成肽键时不会发生消旋化。
