Description

Description générale

4,4,4-Trifluoro-1-(2-furyl)-1,3-butanedione (furoyltrifluoroacetone, FTFA) is a β-diketone. Its cytotoxic activity against human cultured tumor and normal cells has been evaluated. Reports suggest that 4,4,4-trifluoro-1-(2-furyl)-1,3-butanedione partially inhibits the oxidation of ferrocyanide in ETP (electron transport particles) isolated from beef heart mitochondria. Its reaction with N,N,N′,N′-tetramethylalkyl diamines to form ionic adducts has been investigated. The conformational analysis of the enol and keto form of FTFA has been reported.

Application

4,4,4-Trifluoro-1-(2-furyl)-1,3-butanedione (tfa) may be used in the following studies:

• As capping ligand in the synthesis of [Eu(tfa)₃]₂bpm complexes (bpm=2,2′-bipyrimidine).
• As reagent in the multistep synthesis of [¹³CD₂]benzylamine.
• As reagent in the synthesis of 3-trifluoromethyl-2-arylcarbonylquinoxaline 1,4-di-N-oxide derivatives by reacting with corresponding benzofurazan oxides.
• In the efficient syntheses of perfluoroalkyl substituted azoles.
• Synthesis of 2-arylcarbonyl-3-trifluoromethylquinoxaline 1,4-di-N-oxide derivatives.
