摘要
以肉桂酸为目标产物,通过逆合成分析、合成设计,采用不同的实验方法合成制备,介绍了水相Heck反应、无溶剂Perkin反应、水相Wittig反应、水相Knoevenagel反应,拓展了学生的合成设计思维。本实验涵盖了目标产物的合成、纯化与表征,让学生认识和完成了一个基本的科研过程,提高了学生的综合能力。
This article focuses on the synthesis of cinnamic acid. Retrosynthetic analysis and synthetic design have shown that the construction of cinnamic acid can be achieved by several protocols, including the aqueous Heck reaction, the solvent-free Perkin reaction, the aqueous Wittig reaction and the aqueous Knoevenagel reaction. These protocols extend the synthetic design thinking of students. These experiments cover the synthesis, purification and characterization of cinnamic acid, helping students understand and complete a basis scientific research process;thus, students’ comprehensive ability is improved.
