| 编号: | 179548 |
| 中文名称: | Z-Asp(OtBu)-甲酯化 |
| 中文同义词: | L-正亮氨酸 |
| 英文名: | L-Norleucine |
| 英文同义词: | N-ALPHA-CARBOBENZOXY-L-ASPARTIC ACID-βT-BUTYL ESTER ALPHA-METHYL ESTER |
| CAS号: | 63327-57-1 |
| 单字母: | Z-D(OtBu)-OMe |
| 三字母: | Cbz N端Cbz保护,苄氧羰基(Cbz,Z) -Asp(OtBu)侧链OtBu保护的天冬氨酸 -OMeC端甲酯化修饰,甲酯是最简单的酯类,在溶液合成中作为重要的半永久性C端保护基团。它们可以转化为肽肼,而肽肼是反应性肽叠氮化物的先驱体。叠氮偶联仍是肽溶液合成中片段偶联最常用的方法。 |
