Description

(1) Technical field

[0001] The present invention relates to 3-substituted cyclopropanylpyrrolidine-2,4-dione compounds and their herbicidal activity. (2) Background technology

[0002] 4-hydroxyphenylpyruvate dioxygenase (4-hydroxyphenylpyruvate dioxygenase, HPPD) exists in various organisms and has been extracted. It is an iron-tyrosine protein that can catalyze p-hydroxypyruvate in plants. It is converted into homogentisic acid, and then converted into plastoquinone and tocopherol, which are important substances required for electron transfer in photosynthesis. Among them, plastoquinone is also a key auxiliary factor affecting the catalysis of phytoene desaturase. In view of its above-mentioned important At the same time, because the enzyme inhibitor 2-(2-nitro-4-trifluoromethylbenzoyl-1,3-dione has been used in the clinical treatment of tyrosinosis, it has no adverse effects on the human body function, making it another new herbicide target enzyme after ALS, ACC and Prot...
