General description

2,3-Pentanedione (acetylpropionyl) is one of the aroma active compounds of cereal coffee brew.

Application

2,3-Pentanedione can be used as a reactant to synthesize:
  • Bisphenol derivatives by acid-catalyzed condensation reaction with phenols.
  • 2-Ethyl-3-methyl-1H-indole by Pd-catalyzed reaction with aniline under reductive conditions.
  • 2-Ethyl-3-methylquinoxaline by condensation reaction with o-phenylenediamine using citric acid as a catalyst.

The reaction of pigeon liver malic enzyme (L-malate:NADP+ oxidoreductase (oxaloacetate-decarboxylating), EC 1.1.1.40) with dicarbonyl compounds (2,3-butanedione, methylglyoxal, 2,4-pentanedione, and phenylglyoxal) resulted in a rapid loss of its enzymatic activity. The inactivation showed pseudo-first-order kinetics for all the dicarbonyls studied. All
