Abstract:
A compound of formula (I) or an agriculturally, horticulturally, pharmaceutically or veterinarily acceptable salt thereof: wherein:R1 represents a methyl group, ethyl group, isopropyl group or s-butyl group; R2 represents a hydrogen atom or an alkyl group having from 1 to 6 carbon atoms; R3 represents a hydrogen atom, an alkanoyl group having from 1 to 6 carbon atoms which may optionally be substituted with 1, 2 or 3 substitutents selected independently from Substituents A defined below, an alkenoyl group having from 3 to 5 carbon atoms which may optionally be substituted with 1 or 2 substitutents selected independently from Substituents A defined below, an alkynoyl group having from 3 to 5 carbon atoms which may optionally be substituted with 1 or 2 substitutents selected independently from Substituents A defined below, an alkylsulfonyl group in which the alkyl moiety has from 1 to 6 carbon, or an alkoxycarbonyl group in which the alkoxy moiety has from 1 to 6 carbon atoms, or R2 and R3 together with the nitrogen atom to which they are attached form a saturated 4- to 6-membered heterocyclic ring group containing one ring nitrogen atom and optionally containing one further ring heteroatom selected from the group consisting of sulfur atoms, oxygen atoms and nitrogen atoms, said saturated heterocyclic ring optionally being substituted with 1 or 2 substituents independently selected from Substituents B defined below; the moiety -a- together with the carbon atom to which it is attached forms a 3- to 6-membered cycloalkyl group; Substituents A are selected from the group consisting of halogen atoms, cyano groups, hydroxy groups, alkoxy groups having from 1 to 6 carbon atoms, alkylthio groups having from 1 to 6 carbon atoms, alkanoyloxy groups having from 1 to 6 carbon atoms, amino groups which may optionally be substituted with 1 or 2 substituents selected from the group consisting of alkyl groups having from 1 to 6 carbon atoms atoms, alkanoyl groups having from 1 to 6 carbon atoms, alkylsulfonyl groups in which the alkyl moiety has from 1 to 6 carbon and alkoxycarbonyl groups in which the alkoxy moiety has from 1 to 6 carbon atoms, and saturated 4- to 6-membered heterocyclic ring groups containing one ring nitrogen atom and optionally containing one further ring heteroatom selected from the group consisting of sulfur atoms, oxygen atoms and nitrogen atoms, said heterocyclic ring groups optionally being substituted with 1 or 2 substituents independently selected from Substituents B defined below; Substituents B are selected from the group consisting of halogen atoms, cyano groups, hydroxy groups, alkoxy groups having from 1 to 6 carbon atoms, alkylthio groups having from 1 to 6 carbon atoms, alkanoyloxy groups having from 1 to 6 carbon atoms, amino groups which may optionally be substituted with 1 or 2 substituents selected from the group consisting of alkyl groups having from 1 to 6 carbon atoms atoms, alkanoyl groups having from 1 to 6 carbon atoms, alkylsulfonyl groups in which the alkyl moiety has from 1 to 6 carbon and alkoxycarbonyl groups in which the alkoxy moiety has from 1 to 6 carbon atoms and oxo groups.
