BOC-L-4-硝基苯丙氨酸在有机合成转化中表现出特定的化学行为:其结构中的硝基可以在钯碳加氢的作用下还原成氨基;同时,在一定条件下,羧基可以被还原为羟基而不会影响硝基。此外,羧基还可以容易地转化为酰胺基团。
用途BOC-L-4-硝基苯丙氨酸在常温常压下是一种米色固体粉末,主要用作有机合成和医药化学中的中间体,并可用于合成多肽类药物。
合成方法向(S)-4-硝基苯基丙氨酸(2.00克,9.51毫米摩尔)溶解于2M氢氧化钠水溶液(10毫升)和四氢呋喃(5毫升)的混合液中,加入二叔丁基二碳酸酯(2.00克,9.17毫米摩尔),在室温下搅拌反应1小时。随后,用25毫升水和25毫升1M盐酸稀释反应混合物,并使用乙醚(3 x 25毫升)进行萃取。合并的乙醚层用25毫升盐水洗涤一次后,分离出有机层并使用无水硫酸镁干燥。过滤除去硫酸镁固体后,将滤液在减压下浓缩即可得到目标产物BOC-L-4-硝基苯丙氨酸,产量为2.51克,产率为88%。
