응용 분야
용도Ethyl benzoylacetate (Best) is used as intermediate for different organic synthesis. Product Data Sheet
일반 설명Ethyl 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.
제조 방법
By condensation of ethyl benzoate with ethyl acetate (via Claisen condensation) using sodium ethoxide; another method also known.
