摘要
席夫碱化合物具有多功能性,与中心原子形成配位形成金属配合物,使得它成为近代科学研究的热点.本文主要介绍以黄连素为原料,经Vilsmeier-Haak试剂(DMF/POCl_3)甲酰化,最后分别与水合肼、盐酸羟胺反应,生成黄连素席夫碱.本文探讨了黄连素甲酰化的最佳反应条件,中间体和产物分别用UV、IR进行了表征.
Schiffbase compounds are mufti-functional, which has become a hot subject in contemporary research. This paper mainly introduces the process of synthesizing the Schiff base： with the berberine as raw material, after Vilsmeier-Haak reagent （DMF/POCl3） formylation, the formyl-berberine of intermediate was obtained. New Schiffs bases were synthesized by reaction with the intermediate and hydrazine hydrate, hydroxylamine hydrochloride respectively. The intermediate and Chiff bases were characterized by UV, IR.
