suitability of the 2-cyano group for the protection of carboxylic functions in peptide synthesis, we have obtained the 2-cyanoethyl esters of a number of amino acids and have studied their behavior under the conditions of peptide synthesis. The synthesis of the pentapeptide leucine-enkaphalin has been performed with the use of 2-cyanoethyl protection for C-terminal carboxygroups throughout. The physicochemical
为了研究 2-氰基在肽合成中保护羧基官能团的适用性,我们获得了许多氨基酸的 2-氰基乙酯,并研究了它们在肽合成条件下的行为。五肽亮氨酸-脑啡肽的合成是在整个 C 端羧基使用 2-氰乙基保护的情况下进行的。给出了合成化合物的理化特性。
