Abstract:β-Keto esters is a series of important and versatile intermediates in organic synthesis. In this paper,an economical method with high yield for the preparation of β-keto ester was developed starting from diethyl malonate via potassium ethyl malonate,which was reacted with acyl chloride under catalysis of anhydrous magnesium chloride-triethylamine system. This process avoids using of Grignard reagent,sodium hydride and n-butyl lithium. Therefore it can be conducted under mild conditions with low costs and suitable for commercial production of β-keto esters with high purity.
Key words:β-keto ester;potassium ethyl malonate;magnesium chloride-triethylamine;synthesis
