摘要： An isoxazoline compound with optical activity is shown in the formula (I). The compound of the formula (I) has excellent herbicidal activity, can be used for weeding pre- and post-emergence, and can also be used for soil treatment. The compound of the formula (I) can effectively control various broad-leaved weeds, grass weeds and Cyperaceae weeds, and can control various resistant weeds, such as glyphosate-resistant weeds. The excellent weeding effect can be obtained at a low dose. The compound has good safety to crops such as corn, wheat, rice, soybean and sugar beet. The compound can be used as a selective herbicide in crop fields in agriculture, and can also be used as a non-selective herbicide in non-cultivated land, fallow land, woodland, orchards and ridges.

摘要： A method for preparing an intermediate of a uracil compound containing isooxazoline includes the steps of: making 3-amino-4,4,4-trifluorocrotonic acid methyl ester react with substituted aryl carbamate; in a reaction process, continuously evaporating water and byproduct alcohol in the system; and conducting processing to obtain the intermediate of the uracil compound containing isooxazoline. Using this method the selectivity of the reaction and the utilization rate of raw materials are improved; the hydrolysis products, impurities and tar are reduced; the reaction time is greatly shortened; and the productivity is improved. After one recrystallization of crude products, an intermediate product with purity of more than 97% can be obtained, and quantitative yield can be more than 85%.
