The invention relates to compounds of the formula ##STR1## wherein A together with the two carbon atoms denoted by .alpha. and .beta. is one of the residues ##STR2## Q is one of the residues ##STR3## R.sup.1 and R.sup.2 each independently are hydrogen, lower alkyl, lower alkenyl, lower alkynyl, lower hydroxyalkyl, lower alkoxy-lower alkyl, (C.sub.3 -C.sub.6)-cycloalkyl, (C.sub.3 -C.sub.6)-cycloalkyl-lower alkyl, amino-lower alkyl, lower alkylamino-lower alkyl, di-lower alkylamino-lower alkyl or aryl-lower alkyl or together with the nitrogen atom are a 5- to 8-membered membered heterocycle optionally containing a further hetero atom or a fused benzene ring, R.sup.3 is hydrogen and R.sup.4 is lower alkyl or R.sup.3 and R.sup.4 together are dimethylene or trimethylene and R.sup.5 and R.sup.6 each independently are hydrogen, halogen, trifluoromethyl, lower alkoxy or nitro, the compounds of formula I having the (S) configuration with reference to the carbon atom denoted by .gamma. when R.sup.3 and R.sup.4 together are dimethylene or trimethylene, and pharmaceutically acceptable acid addition salts thereof. These compounds and salts have pronounced anxiolytic, anticonvulsant, muscle relaxant and sedative-hypnotic properties.
本发明涉及具有以下公式的化合物:##STR1## 其中A与标记为α和β的两个碳原子共同构成##STR2##中的一个残基;Q是##STR3##中的一个残基;R1和R2各自独立地为氢、低级烷基、低级烯基、低级炔基、低级羟基烷基、低级烷氧基-低级烷基、(C3-C6)-环烷基、(C3-C6)-环烷基-低级烷基、氨基-低级烷基、低级烷基氨基-低级烷基、二低级烷基氨基-低级烷基或芳基-低级烷基,或者与氮原子共同形成一个含有另外一种杂原子或一个融合的苯环的5至8成员的杂环;R3是氢,R4是低级烷基,或者R3和R4共同是亚甲基或三亚甲基;R5和R6各自独立地为氢、卤素、三氟甲基、低级烷氧基或硝基;当R3和R4共同是亚甲基或三亚甲基时,相对于标记为γ的碳原子,本发明的公式I化合物具有(S)构型,以及它们的药物可接受的酸加成盐。这些化合物和盐具有显著的抗焦虑、抗惊厥、肌肉松弛和镇静催眠性质。
