  Synthesis and Herbicidal Evaluation of Triketone-Containing Quinazoline-2,4-diones

  摘要：

  Exploring novel 4-hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, HPPD) inhibitors is one of the most promising research directions in herbicide discovery. To discover new triketone herbicides with broad-spectrum weed control as well as excellent crop selectivity, a series of (total 52) novel triketone-containing quinazoline-2,4-dione derivatives were synthesized and further bioevaluated. The greenhouse testing indicated that many of the newly synthesized compounds showed better or excellent herbicidal activity against broadleaf and monocotyledonous weeds at the dosages of 37.5150 g of active ingredient (ai)/ha. The structure and activity relationship in this study indicated that the triketone-containing quinazoline-2,4-dione motif has possessed great impact on herbicide activity and may be used for further optimization. Among the new compounds, III-b and VI-aVI-d displayed a broader spectrum of weed control than mesotrione. In addition, the compound III-b also demonstrated comparatively superior crop selectivity to mesotrione, thus possessing great potential for weed control in the field.
