  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.

  Themisone, also known as Atrolactamide, was found, in the 1950s, to be a very potent anticonvulsant. It was hypothesized that the -CF(3) substitution would maintain the anticonvulsant activity. Anticonvulsant testing of our novel compounds by the National Institute of Health's Anticonvulsant Screening Project of the Antiepileptic Drug Discovery Program identified analogue 1, 3,3,3-trifluoro-2-hydr

  An unprecedented NHC-catalyzed generation of p-quinodimethanes via ε-umpolung of 4-(chloromethyl)benzaldehydes and the following ε-addition to active ketones was developed. A series of active ketones, such as trifluoromethyl ketones and 1,2-dicarbonyl compounds, worked well for the reaction, giving the corresponding trifluoromethyl alcohols and α-hydroxyl carbonyl compounds in good yields.
