ABSTRACT A series of new fatty N-acyl trihalomethylated pyrazoline derivatives from fatty acid methyl esters was synthesized by the cyclocondensation of respective fatty hydrazides with 4-alkoxy-1, 1, 1-trialomethyl-3-alquen-2-ones. Efficient and regiospecific cyclizations catalyzed by BF 3· MeOH gave the desired products in good to excellent yields and at high purity.
