Lithiation at the C-3 position of 10-methylphenothiazine can be achieved by a BusLi–Br exchange reaction starting from 3-bromo-10-methylphenothiazine. Reaction of the lithiated species with different electrophiles gives rise to different new and well known compounds which due to their radical properties are important enzyme enhancers. The described procedure gives moderate to high yield and easy access to C-3 substituted derivatives.
从 3-溴-10-甲基吩噻嗪开始,通过 BusLi-Br 交换反应可实现 10-甲基吩噻嗪 C-3 位置的石碳酸化。石碳酸化物与不同的亲电体发生反应,会产生不同的新化合物和众所周知的化合物,这些化合物因其自由基特性而成为重要的酶促进剂。所描述的程序可提供中等到较高的产率,并易于获得 C-3 取代的衍生物。
