制备方法与用途

应用

4-溴-2-甲基苯酚主要用作有机合成与医药化学中间体。它可用于药物分子和消毒剂的合成以及实验室科学研究。

制备

将1 mmol邻甲基苯酚溶于3 mL乙醇中,然后向混合物中加入1.02 mmol重结晶提纯的N-溴代丁二酰亚胺。所得混合物在室温下搅拌1分钟,并用薄层色谱(TLC)监测反应进程,确保原料完全反应后,在减压下除去乙醇溶剂。

接着向反应体系中加入10 mL乙酸乙酯和10 mL蒸馏水,将混合物转移至分液漏斗中。分离有机相(乙酸乙酯),并用2 × 7 mL的乙酸乙酯萃取水层。合并所有乙酸乙酯提取物,并使用无水硫酸镁干燥。最后,通过旋干有机溶剂得到粗产物,再经柱层析分离纯化即可获得目标产物4-溴-2-甲基苯酚。

    研究发现,来自三叶类多毛A蛇Amphitrite ornata的多功能催化血红蛋白脱卤过氧化物酶(DHP)可以催化H 2 O 2依赖性的EPA优先污染物(4- Me - o-甲酚,4-Cl- m-甲酚和五氯酚)的氧化。EPA有毒物质控制法案化合物(ø - ,米- ,p甲酚和4-氯离子ö甲酚)。生化分析(HPLC / LC-MS)表明形成了多种氧化产物,包括相应的邻苯二酚,2-甲基苯醌(2-MeBq)和氧化和/或脱卤程度不同的低聚物。使用4-BR- Ø-甲酚作为代表性底物,用18 O进行标记研究证实掺入邻苯二酚的O原子仅来自H 2 O 2,而掺入2-MeBq的O原子则来自H 2 O,与此一致单个底物分别被过氧合酶和过氧化物酶机制氧化。停止流动的紫外可见光谱研究强烈暗示了化合物I在导致儿茶酚形成的过氧化酶机制中的作用,以及化合物I和ES在产生2-MeBq产物的过氧化物酶机制中的作用。DHP与4-F-邻甲酚(1
