Thus, a recently synthesized quioxaline derivative which showed reduced side-effects in an animal model was used as a model-substance. The cyclus was modified to optimize the pharmacological profile. Accordingly, a series of imidazo-thieno-thiazines was synthesized starting from 5-acetyl-2-chloro-3-nitrothiophene to yield 6-ethyl-2,3-dihydro-1 H -thieno[2,3- b ][1,4]thiazine-2-one.

GABA 受体配体在药物开发中仍然非常有趣。通常在治疗中使用苯二氮卓类药物,但它们有严重的副作用。因此,最近合成的在动物模型中显示出减少的副作用的喹喔啉衍生物被用作模型物质。修改了睫毛以优化药理作用。因此,从5-乙酰基-2-氯-3-硝基噻吩开始合成了一系列咪唑并噻吩并噻嗪,得到6-乙基-2,3-二氢 -1H- 噻吩并[2,3- b ] [1 ,4]噻嗪-2-一。与 叔丁醇钾和氯 磷酸二乙酯反应生成 中间体,在加入相应的异氰酸酯和钾后得到所需的环系 叔 丁醇盐。
