摘　　要：设计并合成了３种含有巴比妥酸基团的具有电子给－受体结构的两亲性有机分子，经元素分析、红外光谱、核磁共振谱确定了其结构，研究了醛与巴妥酸缩合的条件及醛的反应活性与其ＩＲ、ＮＭＲ谱的关系。Three electron donor-acceptor amphiphilic compounds with barbituric acid were designed and synthesized.All the compounds have not been reported so far and their structures have been confirmed by elementary analysis,1H NMR and IR.The reactions of aldehydes with barbituric acid were studied,and it is found that,in the basic media,the reaction rates were immeasurably slow,however,in the neutral media,the rates were very fast.The relationship among reaction activities of aldehydes,the NMR chemical shifts of their hydrogens connected with carbonyl group,and their carbonyl groups characteristic infrared absorption,were also studied.
