Pesticidal compounds have the formula:
wherein D represents hydrogen or a cyano group or an ethynyl group
R8 represents alkyl
A represents an alkyl group or a halogeno or trifluoromethyl group
n is 0 or an integer of 1-4, b is 0 or 1 and
RCOO is the residue of an acid RCOOH whose a-cyano-3-phenoxybenzyl ester has pesticidal properties. They are prepared by esterification methods.

A compound of formula I
in which formula:
Ra represents hydrogen or a C1-C6 alkyl group, and Rc represents a C1-C6 alkyl group;
Rb represents a phenyl group, optionally substituted by a C1-C6 alkyl group or halogen, a group of formula -CH=CRdR. in which Rd and R., which may be identical or different represent hydrogen or C1-C6 alkyl groups or a group of formula -CH=NORf in which Rf represents hydrogen or a C1-C6 alkyl group and
RCOO represents a residue of an acid RCO2H, which acid, or an ester-forming derivative of which acid, on reaction with a-cyano-3-phenoxybenzyl alcohol or an ester forming derivative thereof, give rise to an a-cyano-3-phenoxybenzyl ester having pesticidal properties.
In research focused on protein–proteininteraction (PPI) inhibitors, the optimization process to achieve both high inhibitory activity and favorable physicochemical properties remains challenging. Our previous study reported the discovery of novel and bioavailable Keap1-Nrf2 PPI inhibitor 8 which exhibited moderate in vivo activity in rats. In this work, we present our subsequent efforts to optimize
