Uses

Ethyl benzoylacetate (Best) is used as an 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.

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.

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.
