New heterocyclic compounds having the general formula ##STR1## wherein ##STR2## CO.sub.2 R' or CONR'R", wherein R' and R" independently are C.sub.1-6 -alkyl, C.sub.3-7 -cycloalkyl or C.sub.1-6 -alkoxymethyl; --A-- is --C(.dbd.O)--NR'"--, --NR'"--C(.dbd.O)--, or ##STR3## wherein R'" is C.sub.1-6 -alkyl; X is C or N; and R.sup.4 is hydrogen, halogen, CN, C.sub.1-6 -alkyl, C.sub.1-6 -alkynyl, trimethylsilyl-C.sub.1-6 -alkynyl, aryloxy which may be substituted with halogen, aralkoxy, C.sub.3-7 -cycloalkoxy which may be substituted with one or more C.sub.1-6 -alkyl groups, or NR""R'"", wherein R"" and R'"" independently are C.sub.1-6 -alkoxy or together with the nitrogen atom form a 3-7 membered heterocyclic ring. The compounds are useful in psychopharmaceutical preparations as anticonvulsants, anxiolytics, hypnotics, and nootropics.
新的杂环化合物具有一般公式##STR1##其中##STR2## CO.sub.2 R'或CONR'R",其中R'和R"独立地为C.sub.1-6-烷基,C.sub.3-7-环烷基或C.sub.1-6-烷氧甲基;--A--为--C(.dbd.O)--NR'"--,--NR'"--C(.dbd.O)--,或##STR3##其中R'"为C.sub.1-6-烷基;X为C或N;R.sup.4为氢,卤素,CN,C.sub.1-6-烷基,C.sub.1-6-炔基,三甲基硅基-C.sub.1-6-炔基,可能被卤素取代的芳基氧,芳基氧基,C.sub.3-7-环烷氧,可能被一个或多个C.sub.1-6-烷基基团取代的NR""R'",其中R""和R'""独立地为C.sub.1-6-烷氧基,或者与氮原子一起形成3-7成员杂环环。这些化合物在精神药物制剂中作为抗癫痫药、抗焦虑药、催眠药和脑功能增强剂中很有用。
