使用Ethyl benzoylacetate (Best) is used as intermediate for different organic synthesis. Product Data Sheet

一般的な説明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.

調製方法

製造方法By condensation of ethyl benzoate with ethyl acetate (via Claisen condensation) using sodium ethoxide; another method also known.
