unexpected enantioselective 1,2-aldol reaction of acetone with α,β-unsaturated trifluoromethylketone catalyzed by l-proline derivative was described. The absolute configuration of the resulting chiral product was assigned based on a single crystal X-ray diffraction analysis. Structure–reactivity study of this organocatalytic system was briefly discussed. A reaction mechanism was tentatively postulated

A methodology for regioselective synthesis of 3-trifluoromethylpyrazole from the reaction of trifluoromethyl alkenone and tosylhydrazone has been developed. The reaction was proposed to proceed through a tandem cyclization and 1,5-H shift reaction, which can be applied to the synthesis of bioactive compounds like Celecoxib, Mavacoxib, and SC-560.

to 1-(trifluoromethyl)furanderivatives is reported. 4-Aryl-1,1,1-trifluorobut-3-en-2-one was iodinated and subsequently reduced to give the corresponding alcohol. The resultant iodo compound was then subjected to coupling with phenylacetylene to furnish an (E)-3-aryl-2-(2-phenylethynyl)-1-(trifluoromethyl)allyl alcohol, which could be cyclized by means of AgOTf to furnish a 2-(trifluoromethyl)furan

4-Ethoxy-1,1,1-trifluoro-3-buten-2-one (1) reacts with phenylmagnesiumbromide to give ethoxy group substitution products while the reaction of 1 with organozinc compounds gives products arising from 1,2-addition to the carbonyl group. Enone 1 reacts with electron-rich aromatic systems such as indole and N,N-dimethylaniline in the presence of a Lewis acid catalyst to give a β-arylvinyltrifluoromethylketone
