Ten beta-trifluoroalkyl aminovinyl ketone derivatives were synthesized, and their inhibitory effects on several phytopathogenic fungi, an oomycete and plants were assessed. The various compounds were fungitoxic at the 10-100 mu M range, with (Z)-3-amino-4,4,4-trifluoro-1-(4-chlorophenyl)but-2-en-1-one exhibiting the highest inhibitory effect on most of the test pathogens. Alternaria alternata and Neurospora crassa were the most tolerant and sensitive fungi to the compounds, respectively. We propose that (Z)-3-amino-4,4,4-trifluoro-1-phenylbut-2-en-1-one is the minimal structural requirement for a beta-trifluoroalkyl aminovinyl ketone fungitoxic derivative.

ring-cleavage of isoxazoles to yield fluoroalkylated enaminones. This protocol has the advantage of using commercially available reagents, ease of setting up, broad tolerance of functionality, and is regiospecific and free of defluorination and reduction of reducible functional groups. The utility was demonstrated by a one-step, regioselective synthesis of fluoroalkylated pyrazole-based drugs such as celecoxib
Reactions of aromatic and heteroaromatic β-amino-β-polyfluoroalkylvinyl ketones with ethylenediamine. A new synthesis ofN,N′-unsubstituted imidazolidines

The reactions of aromatic and heteroaromatic β-amino-β-polyfluoroalkylvinyl ketones with ethylenediamine results in the formation of 2,3-dihydro-1H-1,4-diazepines,N,N′-unsubstituted imidazolidines, orN,N′-ethylenebis(aminovinyl ketones). The reaction route depends on the reaction conditions, the nature of the substituent at the carbonyl group, and the number of fluorine atoms in the polyfluoroalkyl
