General description
Ethyl benzoylacetate is an ester. It undergoes microbial reduction by bakers′ yeast (Saccharomyces cerevisiae), Beauveria sulfurescens or Geotrichum candidum to afford ethyl (S)-3-hydroxy-3-phenylpropionate. It undergoes Claisen condensation reaction with malononitrile to afford 2-cyano-5-phenyl-3,5-dioxopentanonitrile which on cyclization followed by coupling with diazonium salts yields azo derivatives.
Application
Ethyl benzoylacetate was sed in the preparation of:
- triazipinones
- ethyl 2-fluoro-2-benzolyacetate
- 1,2,4-triazolo[1,5-a]pyrimidine antibiotic essramycin
- benzo[c]furan-4,7-diones
- iodonium ylides
