A convenient method for the synthesis of high-boiling-point α-(trifluoromethyl)styrenes was proposed. The regioselective synthesis of a series of ethyl 5-aryl-5-(trifluoromethyl)-4,5- dihydroisoxazole-3-carboxylates was conducted by the reaction of ethyl nitroacetate with α-(trifluoromethyl)styrenes in the presence of 1,4-diazabicyclo[2.2.2]octane as a catalyst. The effect of the resulting compounds on seed germination and root formation was studied.

Key words
