In order to discover green herbicides with novel molecular scaffolds, natural tetramic acids were used as lead compounds to design and synthesize four pyrrolidine-2,4-dione derivatives incorporating a chainlike alkoxyalkyl moiety (4a-4d) and nineteen pyrrolidine-2,4-dione derivatives incorporating a substituted phenoxyethyl moiety (10a-10s)viasubstitution, acylation, cyclization, and acidification reactions. The synthesized target compounds were confirmed by FT-IR,1H NMR,13C NMR and HRMS spectral analyses. The single-crystal structure of compound10awas analyzed by X-ray diffraction, which revealed that the 1-hydroxyethylidene group links the third position of the pyrrolidine heterocycle through a double bond with theZ-configuration. The herbicidal activity was evaluated using barnyard grass (Echinochloa crus-galli) and rape (Brassica campestris) as model plants by a Petri dish culture method. Most target compounds were found to possess moderate to good inhibitory activities against the plant growth at 100 μg mL?1. Among them, the compounds10qand10nshowed the highest herbicidal activities against the roots of barnyard grass and rape seedlings with the corresponding inhibition rates of 65.6% and 84.0%, respectively. This result indicated that pyrrolidine-2,4-dione derivatives incorporating a substituted phenoxyethyl moiety are worthy of further structural optimization.

We report the identification of a novel series of trisubstituted isoxazoles as PPAR activators from a high-throughput screen. A series of structural optimizations led to improved efficacy and excellent functional receptor selectivity for PPARδ. The isoxazoles represent a series of agonists which display a scaffold that lies outside the typical PPAR agonist motif.
