Claims17
A compound of formula I, or a salt or a cis/trans isomer thereof:
- wherein:
- R1 is phenyl, which may be substituted or unsubstituted;
- R2 is hydrogen;
- R3 and R4 together form a 5-membered nitrogen heterocycle fused with a benzene ring, each of which may themselves be substituted or unsubstituted;
- and
- R5 is selected from C1 to C20 haloalkyl, C1 to C20 haloalkenyl, a fluorine-containing group, C1 to C20 secondary or tertiary alkyl wherein secondary and tertiary are defined at the carbon attached to the carbonyl carbon of formula I, C2 to C20 alkenyl, ester, amide, C1 to C20 alkanoyl, C1 to C20 alkenoyl, aryl, C5 to C7 cycloalkenyl, or heterocyclic, each of which groups may be substituted or unsubstituted.
