    • 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 amination reaction of the isoxazolines.
    • 本发明涉及一种制备式(Ⅷ)卤代苯乙烯化合物的新方法,它是在合成式(I)的取代的异恶唑啉化合物的方法中的前体,其中R1至R5,R8和R9如说明书所述。 本发明还涉及从苯乙酮开始合成式(I)化合物。 所需的配方苯乙烯由合适的取代苯乙酮制备。 溴代苯胺与甲肟反应。 获得的肟与苯乙烯进行环加成并得到异恶唑啉。 然后可以在异恶唑啉的钯催化的羰基化胺化反应中制备式(I)化合物。
