Novel 4-Benzazonine derivatives and their salts, and processes for the preparation thereof are disclosed. These 4-benzazonine derivatives are represented by the following general formula: ##STR1## wherein R stands for --H, --OH or a lower alkoxy group such as --OCH.sub.3, R.sub.1 designates --H or a lower alkyl group such as --CH.sub.3 and --CH.sub.2 CH.sub.3, R.sub.2 indicates --H or a lower alkyl group such as --CH.sub.3, R.sub.3 stands for --H, a linear or branched, saturated or unsaturated alkyl group having 1 to 4 carbon atoms, a mono- or di-hydroxy lower alkyl group such as --CH.sub.2 OH and ##STR2## a saturated cyclic hydrocarbon group having 3 to 6 carbon atoms or a substituted or unsubstituted aromatic hydrocarbon group having 6 to 8 carbon atoms, and R.sub.4 designates --H, --OH or = O. These compounds have medicinal effects, especially therapeutic activities on the central nervous system, such as analgesic, antitussive and sedative activities.
本发明涉及一种4-苯基氮杂环衍生物及其盐的制备方法。这些4-苯基氮杂环衍生物由下列一般式表示:##STR1## 其中,R代表--H、--OH或较低的烷氧基,如--OCH.sub.3,R.sub.1代表--H或较低的烷基,如--CH.sub.3和--CH.sub.2 CH.sub.3,R.sub.2表示--H或较低的烷基,如--CH.sub.3,R.sub.3代表--H、线性或支链的、饱和或不饱和的碳数为1到4的烷基、单或双羟基较低的烷基,如--CH.sub.2 OH和##STR2## 饱和的3到6个碳原子的环烃基或有6到8个碳原子的取代或未取代的芳香烃基,R.sub.4代表--H、--OH或=O。这些化合物具有药理作用,特别是对中枢神经系统的治疗活性,如镇痛、止咳和镇静活性。
