is devoted to the synthesis of arylidene malonic acid monoanilides and cinnamoyl anilines by condensation of malonic acid monoanilides with aromatic aldehydes. The presented synthetic route applies simple, cheap, and commercially available aromatic aldehydes and amines, thus overcoming traditional schemes, which involve derivatives of hydroxycinnamic acids. Besides, a mild and effective pyridine-mediated
摘要本文致力于通过丙二酸单苯胺与芳香醛的缩合合成芳基丙二酸单苯胺和肉桂酰基苯胺。提出的合成路线应用简单,便宜且可商购的芳族醛和胺,因此克服了涉及羟基肉桂酸衍生物的传统方案。此外,提出了一种温和有效的吡啶介导的芳基丙二酸丙二酸单苯胺中C sp 2处羧基的羧基脱羧,从而导致肉桂酰基苯胺。通过X射线分析另外批准了所获得的选定的亚芳基衍生物的结构。研究了合成化合物的抗自由基性能(2,2-二苯基-1-吡咯肼基和丙氧基测试)和结构-活性关系。 图形概要
