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.

Two cytosolic NADPH-dependent carbonyl reductases from Gluconobacter oxydans 621H, Gox0644 and Gox1615, were heterologously produced in Escherichia coli. The recombinant proteins were purified to homogeneity and characterized. Gox0644 and Gox1615 were dimers with native molecular masses of 66.1 and 74.5
