  • In an effort to develop novel β-triketone herbicides containing a barbituric acid moiety, a series of 5-acylbarbituric acid derivatives were designed, synthesized, and tested for herbicidal activity. The bioassay results showed that some of the target compounds, such as 5-(2-(2-chloro-4-fluorophenoxy)-1-hydroxyethylidene)-1, 3-dimethylpyrimidine-2, 4, 6(1H, 3H, 5H)-trione (BBA-22) and 5-(2-(2-bromo-4-fluorophenoxy)-1-hydroxyethylidene)-1, 3-dimethylpyrimidine-2, 4, 6(1H, 3H, 5H)-trione (BBA-27), exhibited excellent herbicidal activity against all tested weeds at a dosage of 1500 g·ha-1. In particular, compound BBA-22 displayed good pre-emergent herbicidal activity against Brassica campestris, Amaranthus retroflexus and Digitaria sanguinalis even at a dosage of 187.5 g·ha-1, surpassing that of a commercial herbicide 2, 4-dichlorophenoxyacetic acid (2, 4-D). Investigation of the molecular mode of action of compound BBA-22 upon treatment of Arabidopsis thaliana as a model plant revealed that BBA-22 was degraded to the corresponding phenoxyacetic acid, which explains why the herbicidal mechanism is similar to that of auxin-type herbicides. The present study demonstrates that compound BBA-22 is a proherbicide of the corresponding phenoxyacetic acid auxin herbicide and a potential lead compound for further development of novel auxin herbicides.
