制备方法与用途

应用

2-溴-4-硝基咪唑是一种有机合成中间体和医药中间体，可用于实验室研发过程及化工医药合成过程中。

简介

2-溴-4-硝基咪唑为淡黄色至类白色的粉末状物质，可用作医药中间体。

合成方法

以4-硝基咪唑(VIII)为原料，在水中与碱金属碳酸氢盐作用下与溴化试剂反应得2,5-二溴硝基咪唑(XI)，后者在非质子溶剂中与碘代试剂反应得2-溴-5-碘-2-硝基咪唑(XV)。最后，2-溴-5-碘-2-硝基咪唑(XV)在醇类溶剂中与磷还原试剂进一步反应可得到目标产物2-溴-4-硝基咪唑(II)。

In vitro screening against kinetoplastid diseases revealed that nitroimidazothiazoles were inactive versus leishmaniasis but showed interesting activity, superior to that of the nitroimidazooxazoles, against Chagas disease.
