Synthesis of β‐Keto Esters Promoted by Yttria‐Zirconia Based Lewis Acid Catalyst

Abstract

A variety of aldehydes react with methyl/ethyl diazoacetate in the presence of yttria‐zirconia based catalyst to afford the corresponding β‐keto esters in excellent yields.

Keywords:

• Yttria‐zirconia based Lewis acid
• Heterogeneous catalysis
• Aldehyde
• Diazoacetate
• β‐keto esters
