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, het…
