Novel N-tricyclic derivatives of azetidine are disclosed of the general formula ##STR1## where A is a C.sub.1 -C.sub.3 alkylene group, a C.sub.2 -C.sub.3 alkenylene group or a cyclopropylene group, the remaining substituents being defined in the specification. Such compounds are useful for their anti-depressant, anti-convulsant and anxiolytic activities. The compound 1-[5-(10, 11-dihydro-5H-dibenzo [a,d]cyclopheptenyl)]-3-methyl-amino-azetidine is illustrative.

N-tricyclic derivatives of azetidine and process for their preparation

Novel N-tricyclic derivatives of azetidine of the formula: ##STR1## wherein A is a --CH.sub.2 --O-- or an --O--CH.sub.2 group, and the remaining substituents being defined in the specification are disclosed. An illustrative compound is 1-[11-(6,11-dihydro-dibenzo [b,e] oxepinyl)]-3-methylamino-azetidine. The compounds are useful for their anti-depressant, anti-convulsant and anxiolytic activities.

N-tricyclic derivatives of azetidine

Novel N-tricyclic derivatives of azetidine are disclosed of the general formula: ##STR1## WHERE A is a --CH.sub.2 --S-- or --S--CH.sub.2 -- group, the remaining substituents being defined in the specification. Illustrative is the compound 1-[11-(6,11-dihydro-dibenzo [b,e] thiopinyl)]-3-methylamino-azetidine. The compounds are useful for their anti-depressant, anti-convulsant and anxiolytic activities.

N-tricyclic derivatives of azetidine and pharmaceutical compositions and

1-Oxo-1H-naphtho [ 2,1-b] pyran derivatives, such as, for instance, 1-oxo-3-(N-methyl-N-ethyl) amino-1H-naphtho [2,1-b] pyran, are disclosed, as well as pharmaceutical compositions containing same and the method of treating depression by administering such compositions. These compounds are active on the central nervous system, and therefore function as antidepressive agents.
