Plutella xylostella (P. xylostella) is a highly migratory, cosmopolitan species and one of the most important pest of cruciferous crops worldwide. Pyridalyl as a novel class of insecticides has good efficacy against P. xylostella. On the basis of the commercial insecticide pyridalyl, a series of new aryloxy dihalopropene derivatives were designed and synthesized by using Intermediate Derivatization Methods. Their chemical structures were confirmed by 1H NMR, high-resolution mass spectrum (HRMS), and single-crystal X-ray diffraction analysis. The insecticidal activities of the new compounds against P. xylostella were evaluated. The results of bioassays indicated that most of the compounds showed moderate to high activities at the tested concentration, especially compounds 10e and 10g displayed more than 75% insecticidal activity against P. xylostella at 6.25 mg/L, while pyridalyl showed 50% insecticidal activity at the same concentration. The field trials result of the insecticidal activities showed that compound 10e as a 10% emulsifiable concentrate (EC) was effective in the control of P. xylostella at 75-150 g a.i./ha, and the mortality of P. xylostella for treatment with compound 10e at 75 g a.i./ha was equivalent to pyridalyl at 105 g a.i./ha.

Fifteen novel (3-chloro-5-(trifluoromethyl)pyridin-2-yloxy)phenyl containing Baylis-Hillman adduct derivatives were designed and synthesized. Evaluation of their biological activities showed that methyl 2-((3-(3-chloro-5-(trifluoromethyl)pyridin-2-yloxy)p
Origin of enantiomeric selectivity in the aryloxyphenoxypropionic acid class of herbicidal acetyl coenzyme A carboxylase (ACCase) inhibitors.

Molecular modeling was used to propose an "active conformation" for the R-2-phenoxypropionic acid portion of the aryloxyphenoxypropionic acid series of herbicidal acetyl CoA carboxylase (ACCase) inhibitors. This candidate active conformation is a low-energy conformer with the R-methyl distal to the phenoxy fragment, stabilized by the generalized anomeric effect around the propionate ether bond; the inactive S-enantiomer has difficulty accessing this conformation due to steric interaction of the S-methyl with the o-hydrogen of the phenyl. This candidate conformation was challenged by preparation of a series of novel rigid analogues. ACCase inhibition data suggest that the systems which contain a fused five-membered, but not a six-membered, ring present the necessary pharmacophore to the active site of ACCase, confirming the active conformation hypothesis and demonstrating that the precise placement of the carboxylate relative to the phenyl group is more critical than the placement of the methyl.
