摘要: 以苯胺类化合物为起始原料,经重氮化、丙烯酸加成、氨解等过程合成了5种消旋苯环取代苯丙氨酸衍生物,并采用α-糜蛋白酶和枯草杆菌蛋白酶对所有氨基酸进行了拆分,通过IR,1HNMR,元素分析和旋光等技术进行表征.其中4种氨基酸未见文献报道.

Abstract: Five kinds of racemic ring-modified phenylalanines were synthesized by using aniline derivatives as the raw materials and further characterized with routine analysis. Most of the amino acids were resolved with chymotrypsin or subtilisin and some protected forms of the amino acids were obtained. The possible mechanism of the method for the relatively large scale synthesis was discussed. These unusual amino acids were used as the building blocks for peptide based antagonists. It had latent investigation values that the physicochemical properties and metabolism behavior in vivo of the peptide containing the amino acids were changed.

Key words: Chymotrypsin, Subtilisin, Diazotization, Resolution, Unnatural amino acids, HPLC
