  Process for preparing substituted isoxazoline compounds and their precursors The present invention relates to a new method of preparing halogenated styrene compounds of Formula (VIII), which are precursors in the process of synthesis of substituted isoxazoline compounds of Formula (I), wherein R1 to R5, R8 and R9 are described as in the description. The present invention relates further to the synthesis of compounds of formula (I) starting from acetophenones. The desired styrenes of formula are prepared from the appropriate substituted acetophenone. Asides bromo anilines react with formoxime. Obtained oximes undergo a cycloaddition with the styrenes and give isoxazolines. Compounds of formula (I) can then be prepared in a palladium catalyzed carbonylative ami- nation reaction of the isoxazolines.

  制备取代异恶唑啉化合物及其前体的工艺 本发明涉及一种制备公式(VIII)中卤代苯乙烯化合物的新方法，该卤代苯乙烯化合物是合成公式(I)中取代异恶唑啉化合物的前体，其中R1至R5、R8和R9如说明中所述。本发明进一步涉及从 acetophenones 开始合成公式(I)化合物的过程。所需的公式苯乙烯由相应的取代 acetophenone 制备。除此之外，溴苯胺与甲氧基胺反应。获得的肟与苯乙烯进行环加成并给出异恶唑啉。然后，可以在钯催化的羰基化胺化反应中制备公式(I)的化合物。

  The present invention relates to a new method of preparing halogenated styrene compounds of formula (VIII) which are precursors in the process of synthesis of substituted isoxazoline compounds of formula (I) wherein R 1 to R 5 , R 8 and R 9 are described as in the description. The present invention relates further to the synthesis of compounds of formula (I) starting from acetophenones. The desired styrenes of formula are prepared from the appropriate substituted acetophenone. Asides bromo anilines react with formoxime. Obtained oximes undergo a cycloaddition with the styrenes and give isoxazolines. Compounds of formula (I) can then be prepared in a palladium catalyzed carbonylative amination reaction of the isoxazolines.
