A cyclic amine compound or a salt thereof is defined by the formula:
in which J is
(a) an optionally substituted group selected from (1) phenyl, (2) pyridyl, (3) pyrazyl, (4) quinolyl, (5) cyclohexyl, (6) quinoxalyl and (7) furyl;
(b) a monovalent or divalent group, in which the phenyl may have a substituent(s) selected from the group consisting of (1) indanyl, (2) indanonyl, (3) indenyl, (4) indenonyl, (5) indanedionyl, (6) tetralonyl, (7) benzosuberonyl, (8) indanolyl and (9) C6H5-CO-CH(CH3)-;
(c) a monovalent group derived from a cyclic amide compound;
(d) a lower alkyl; or
(e) a group of R21-CH=CH- in which R21 is hydrogen or a lower alkoxycarbonyl;
B is a bridging group;
T is a nitrogen;
Q is nitrogen, carbon or >N→0;
q is an integer of 1 to 3;
K is hydrogen, an optionally substituted phenyl group, an arylalkyl in which the phenyl may have a substituent, cynnamyl, a lower alkyl, pyridylmethyl, a cycloalkylalkyl, adamantanemethyl, furylmethyl, a cycloalkyl, a lower alkoxycarbonyl or an acyl; and
----¯ shows a single bond or a double bond.
The compound is useful for the preparation of pharmaceutical compositions and for medicaments effective against senile dementia.
