Bicyclic amine derivatives

Abstract

The present invention concerns bicyclic amine derivatives of formula (I): ##STR1## wherein R.sup.1 is an optionally substituted 5-membered heterocyclic ring system containing from 1 to 3 heteroatoms individually selected from nitrogen, oxygen and sulfur atoms, and at least one unsaturation (double bond) between adjacent atoms in the ring, wherein the substutuents, if present, are selected from halogen atoms, alkyl, alkenyl, alkynyl, alkoxy, haloalkyl, haloalkenyl, alkylthio and alkyl amino groups, any of which groups contain up to eight carbon atoms, and wherein two substituents may join to form a fused ring; R.sup.2 represents hydrogen or cyano or a group selected from alkyl, aryl, heteroaryl, aralkyl, heteroarylalkyl, alkenyl, aralkenyl, alkynyl, alkoxycarbonyl, alkanesulfonyl, arenesulfonyl, alkenyloxycarbonyl, aralkyloxycarbonyl, aryloxycarbonyl, heterocyclylalkyl, carbamyl, dithiocarboxyl or XR.sup.3 (where X represents oxygen or a group NR.sup.4), provided that when R.sup.2 is alkenyl, aralkenyl or alkynyl said group does not have an unsaturated carbon atom bonding directly to the ring nitrogen of formula (I); R.sup.3 and R.sup.4 are, independently, hydrogen, alkyl, aryl, heteroaryl, aralkyl, heteroarylalkyl, alkenyl, aralkenyl, alkynyl, heterocyclylalkyl, alkoxycarbonyl or carboxylic acyl; alkyl moieties of R.sup.2, R.sup.3 and R.sup.4 comprise from 1 to 15 carbon atoms, and are optionally substituted with one or more substituents selected from, halogen, cyano, carboxyl, carboxylic acyl, carbamyl, alkoxycarbonyl, alkoxy, alkylenedioxy, hydroxy, nitro, haloalkyl, alkyl, amino, acylamino, imidate and phosphonato groups; or an acid addition salt, quaternary ammonium salt or N-oxide derived therefrom; to processes for preparing them, to insecticidal compositions comprising them and to methods of using them to combat and control insect pests.
