Abstract
Ethyl( E)-3-( 3,4,5-trimethoxyphenyl) acrylate in yield of 86. 7% was synthesized by Knoevenagel condensation from 3,4,5-trimethoxybenzaldehyde and diethyl malomate using Glycine as a catalyst and ethanol as a solvent. The appropriate reaction conditiongs at reflux for 8 h were as follows: 3,4,5-trimethoxybenzaldehyde was 250mmol,n( 3,4,5-trimethoxybenzaldehyde) ∶ n( diethyl malomate) ∶ n( Glycine) =1. 0∶ 1. 6∶ 0. 25,ethanol was 100 mL.
