usefulness of N-carboxy-α-dehydroamino acid anhydride (ΔNCA), the optimum conditions of the acylation of ΔNCA with N-protected α-amino acids (AA) were thoroughly examined. Furthermore, various kinds of AA or dipeptides as a C-component were utilized in the acylation of ΔNCA, followed by condensation with an AA methyl ester as an N-component.
为了进一步开发和扩大N-羧基-α-脱氢
氨基酸酐(ΔNCA)的用途,对ΔNCA与N-保护的
α-氨基酸(
AA)酰化的最佳条件进行了彻底检查。此外,在ΔNCA的酰化中利用各种
AA或二肽作为C-组分,然后与作为N-组分的
AA甲酯缩合。
