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.
