A process for the direct and regioselective functionalization of phenothiazine which allows to introduce an SH group in position 2 is described.
The thus obtained 2-mercapto-phenothiazine is easy transformed into 2-methylthio-phenothiazine, an important intermediate for the preparation of pharmacological active compounds.
本文介绍了一种直接和区域选择性地对吩噻嗪进行官能化的工艺,该工艺可在第 2 位引入一个 SH 基团。
由此获得的 2-巯基吩噻嗪很容易转化为 2-甲硫基吩噻嗪,这是制备药理活性化合物的重要中间体。
