The present invention is concerned with compounds with the formula: ##STR1## in which: R.sub.1 represents a lower alkyl, a lower hydroxy alkyl or a benzyl group, a phenyl group or a 4-hydroxy phenyl group: R.sub.2 and R.sub.3, identical or different, each represents a lower alkyl or hydroxyalkyl, lower alkenyl, or lower alkynyl radical, or together with the nitrogen to which they are attached, they form a saturated heterocycle such as morpholino, thiomorpholino, pyrrolidino unsubstituted or substituted by an alkoxycarbonyl or carboxyl group, piperazino, 4-(lower alkyl)-piperazino, 4-(lower hydroxyalkyl)-piperazino, or piperidino unsubstituted or substituted by a lower alkyl, benzyl, hydroxy, lower hydroxyalkyl, amino, lower aminoalkyl, alkoxycarbonyl or carboxyl group, Ar represents a phenyl, an alpha-naphthyl or a possibly substituted beta-naphthyl group, or a possibly substituted heteroaryl group chosen from pyridyl, quinolinyl, and isoquinolinyl, as well as their stereoisomers and their mixtures and their salts with pharmaceutically acceptable mineral or organic acids. The invention is also concerned with a preparation process for the products with the formula (I), their use as medicaments and the intermediates for their synthesis.
本发明涉及具有以下式的化合物:##STR1## 其中:R.sub.1代表较低的烷基,较低的羟基烷基或苄基,苯基或4-羟基苯基;R.sub.2和R.sub.3,相同或不同,分别代表较低的烷基或羟基烷基,较低的烯基或较低的炔基基团,或者与它们连接的氮一起,形成饱和的杂环,例如吗啡环,硫代吗啡环,吡咯烷未取代或取代的烷氧羰基或羧基,哌嗪,4-(较低烷基)-哌嗪,4-(较低羟基烷基)-哌嗪,或者未取代或取代的哌啶基,其取代基为较低的烷基,苄基,羟基,较低的羟基烷基,氨基,较低的氨基烷基,烷氧羰基或羧基,Ar代表苯基,α-萘基或可能取代的β-萘基或可能取代的杂环基,选择自吡啶基,喹啉基和异喹啉基,以及它们的立体异构体及其混合物和与药学上可接受的矿物质或有机酸盐。本发明还涉及具有式(I)的产品的制备过程,它们作为药物的用途以及它们合成的中间体。
