| | Ethyl benzoylacetate Usage And Synthesis |
| Chemical Properties | Brownish liquid | | Chemical Properties | Ethyl benzoylacetate has a brandy-like odor and sweet, woody, cherry, phenolic-like flavor. | | Uses | Ethyl benzoylacetate (Best) is used as intermediate for different organic synthesis. Product Data Sheet | | Uses | Ethyl benzoylacetate (Benzoylacetic acid ethyl ester) was used to prepare ethyl 2-fluoro-2-benzolyacetate. It was also used to synthesize iodonium ylides. | | Uses | Ethyl benzoylacetate (Best) is used as an intermediate for different organic synthesis Product Data Sheet | | Preparation | By condensation of ethyl benzoate with ethyl acetate (via Claisen condensation) using sodium ethoxide; another method
also known. | | Definition | ChEBI: Ethyl 3-oxo-3-phenylpropanoate is an aromatic ketone. | | Taste threshold values | Taste characteristics at 10 ppm: sweet, cherry, fruity, berry-like with woody, jamy notes. | | Synthesis Reference(s) | Journal of Medicinal Chemistry, 28, p. 1864, 1985 DOI: 10.1021/jm00150a018

The Journal of Organic Chemistry, 38, p. 2731, 1973 DOI: 10.1021/jo00955a040 | | 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. |
