Solvent-Free Enzymatic Synthesis of Ethyl 3-Oxobutyrate Derivative: Characterization and Optimization of Reaction Condition
摘要
It was first found that porcine pancreatic lipase (PPL) could catalyze the Knoevenagel condensation of aromatic aldehydes and ethyl acetoacetate under solvent-free conditions in this paper. Under solvent-free conditions, the highest yield of PPL catalytic reaction was 99.38%, and the Z/E selectivity of the product was 3.93. In addition, the reaction conditions were optimized, and the factors affecting the product structure were studied.
