Abstract
A piperidine compound of the formula (I): ##STR1## wherein A is a fused aromatic ring; R is hydrogen, chloro or methoxy; X is (CH.sub.2).sub.n, which may be substituted, in which n is 0 or an integer of 1 to 10, --CH.dbd.CH--, --C.dbd.C--, --O--, --S--, --NH--, --N(COCH.sub.3)--, --N(COOC.sub.2 H.sub.5)--, --N(CHO)--, --N(CH.sub.3)--, --CO--, --SO--, or --SO.sub.2 --; Y is --CH.dbd.CH--, --CH.sub.2 CH.sub.2 --, --CH.sub.2 CO--, --O--, --S--, --NH--, --OCH.sub.2 --, --SCH.sub.2 --, --NHCH.sub.2 --, --CH(OH)CH.sub.2 -- or --CH(OH)CH(OH)--; and Q is substituted or unsubstituted n-hexyl, carboxypropyl, ethoxycarbonylpropyl, cyanopropyl, cyclohexyl, phenyl, indanyl, naphthyl, tetrahydronaphthyl, benzocycloheptyl, piperidinyl, tetrahydroisoquinolinyl, indolyl, pyrolyl, furyl, thienyl, thiazolyl, oxazolyl or N-methylpyrolyl, wherein any one or more of the --(CH.sub.2)-groups of the hexyl, carboxypropyl, ethoxycarbonylpropyl and cyanopropyl groups may be replaced by --CH.dbd.CH--, --C.dbd.C--, --O--, --S--, --NH--, --N(COCH.sub.3), --N(COC.sub.2 H.sub.5)--, --N(CHO)--, --N(CH.sub.3)--, --CO--, --SO-- or --SO.sub.2 --, and wherein one or more of the --(CH.sub.2)-groups in X and Q may be substituted by --(CH.sub.2).sub.4 -- or --(CH.sub.2).sub.5 -- thereby forming a ring structure.
