The invention concerns compounds of formula ##STR1## and acid addition and quaternary ammonium salts thereof, wherein the dotted line represents an optional bond, Ar represents a ring system of formula ##STR2## in which Q is O,S,--CR.sup.7 .dbd.CR.sup.8 --, --N.dbd.CR.sup.8 -- and --N.dbd.N--; R.sup.4, R.sup.5 and R.sup.6, and R.sup.7 and R.sup.8 when present, each represent hydrogen or defined substituents and additionally either R.sup.4 and R.sup.5 when adjacent or R.sup.6 and R.sup.8 when adjacent, together with the carbon atoms to which they are attached also represent a fused five or six membered carbocyclic or heterocyclic ring optionally carrying one or more defined substituents; R is an optionally substituted aryl or heteroaryl radical or a cycloalkyl radical containing 5 to 7 carbon atoms; R.sup.1, R.sup.2, R.sup.3 and R.sup.9 are each hydrogen or a lower alkyl group; n is 0 or 1; X is .dbd.O, .dbd.S or .dbd.NH; Y is --O-- or a direct bond and Z is --CO-- or --CH.sub.2 -- with the proviso that when Ar is unsubstituted phenyl and R.sup.9 is hydrogen then Y is --O--. The compounds of formula I exhibit psychotropic activity and are useful as antidepressants. Processes for preparing the compounds and pharmaceutical compositions containing them are disclosed.
本发明涉及公式##STR1##的化合物及其酸加成物和季铵盐,其中点线表示可选键,Ar表示式##STR2##的环系统,其中Q为O、S、-CR.sup.7 =CR.sup.8-、-N=CR.sup.8-和-N=N-;R.sup.4、R.sup.5和R.sup.6,以及当存在时,R.sup.7和R.sup.8每个表示氢或定义的取代基,并且当相邻的R.sup.4和R.sup.5或相邻的R.sup.6和R.sup.8与它们连接的碳原子一起也表示融合的五元或六元碳环或杂环,可选地携带一个或多个定义的取代基;R是可选地取代的芳基或杂芳基基团或含有5到7个碳原子的环烷基基团;R.sup.1、R.sup.2、R.sup.3和R.sup.9分别是氢或较低的烷基基团;n为0或1;X为.dbd.O、.dbd.S或.dbd.NH;Y为--O--或直接键,Z为--CO--或--CH.sub.2--,但当Ar为未取代的苯基且R.sup.9为氢时,Y为--O--。公式I的化合物具有精神药物活性,并可用作抗抑郁剂。公开了制备这些化合物和含有它们的制药组合物的方法。
