There are disclosed compounds of the formula ##STR1## wherein R.sup.1 and R.sup.2 are each, independently, hydrogen, alkyl, or phenyl, or R.sup.1 and R.sup.2 taken together represent --(CH.sub.2).sub.4 -- or ##STR2## where the dotted line represents an optional double bond; R.sup.3 is hydrogen, alkyl, alkoxy, or halo; Z is oxygen, or --N(R.sup.6), where R.sup.6 is hydrogen or alkyl; m is 1-4; n is 0-2; ##STR3## wherein R.sup.7 is unsubstituted or substituted phenyl, 2-pyridinyl, 2-pyrimidinyl, 2-pyrazinyl, 3-pyridazinyl, or diphenylmethyl, where the substituents are selected from the group of alkyl, alkoxy, halo, cyano, nitro and trifluoromethyl; R.sup.8 is hydrogen, hydroxy, cyano, alkyl, alkoxy, halo, or NHR.sup.9 where R.sup.9 is hydrogen, alkyl, phenyl, tolyl, xylyl, mesityl, methoxyphenyl, or halophenyl with the proviso when Z is oxygen, R.sup.7 is other than phenyl or pyridyl; or a pharmaceutically acceptable salt thereof, which by virtue of high affinity for the dopamine D-2 receptor and the serotonin 5-HT-.sub.1A receptor, are useful as antipsychotic and anxiolytic agents for the treatment of a variety of central nervous system disorders such as paranoia, schizophrenia, anxiety, sleep disorders, and related problems.
已公开的化合物如下所示:其中R.sup.1和R.sup.2分别独立地为氢、烷基或苯基,或者R.sup.1和R.sup.2一起表示--(CH.sub.2).sub.4 --或##STR2##,其中虚线表示可选的双键;R.sup.3为氢、烷基、烷氧基或卤素;Z为氧或--N(R.sup.6),其中R.sup.6为氢或烷基;m为1-4;n为0-2;##STR3##其中R.sup.7为未取代或取代的苯基、2-吡啶基、2-嘧啶基、2-吡嗪基、3-吡啶啉基或二苯甲基,其中取代基选自烷基、烷氧基、卤素、氰基、硝基和三氟甲基;R.sup.8为氢、羟基、氰基、烷基、烷氧基、卤素或NHR.sup.9,其中R.sup.9为氢、烷基、苯基、甲苯基、二甲苯基、三甲基苯基、甲氧基苯基或卤苯基,但当Z为氧时,R.sup.7不是苯基或吡啶基;或其药用盐。这些化合物由于对多巴胺D-2受体和5-HT-1A受体的高亲和力,可用作治疗各种中枢神经系统疾病的抗精神病和抗焦虑药物,如偏执狂、精神分裂症、焦虑、睡眠障碍及相关问题。
