Novel substituted benzoylacrylanilides are prepared by reacting a substituted benzoylacrylic acid with a substituted aniline in the presence of a coupling agent. These acrylanilides have significant anticoccidial activity.

compounds were synthesized from isorhodanine (4-thioxo-2-thiazolidinone) with ortho-substituted aldehydes, arylidene pyruvic and β-aroylacrylic acids. Michael reaction of isorhodanine with arylidene pyruvic and β-aroylacrylic acids providing 2-oxo-4-(2-oxo-4-thioxothiazolidin-5-yl)-4-phenylbutyric and 4-oxo-2-(2-oxo-2,3-dihydrothiazol-4-ylsulfanyl)-4-phenylbutyric acid is presented. Notably, under
摘要 由异玫瑰丹宁 (4-thioxo-2-thiazolidinone) 与邻位取代的醛、亚芳基丙酮酸和 β-芳酰基丙烯酸合成了各种新型结构多样的噻唑烷酮衍生化合物。异桃醇与亚芳基丙酮酸和 β-芳酰基丙烯酸的迈克尔反应,提供 2-oxo-4-(2-oxo-4-thioxothiazolidin-5-yl)-4-phenylbutyric 和 4-oxo-2-(2-oxo-2,提供了 3-二氢噻唑-4-基硫烷基)-4-苯基丁酸。值得注意的是,在长期加热下,异玫瑰丹宁和 APA 的反应作为迈克尔环化级联进行,导致结构不同的稠合噻喃支架。新合成化合物的结构是通过光谱数据和单晶 X 射线衍射分析确定的。
5-Ethoxymethylidene-4-thioxo-2-thiazolidinone as Versatile Building Block for Novel Biorelevant Small Molecules with Thiopyrano[2,3-<i>d</i>][1,3]thiazole Core
5-Ethoxymethylidene-4-thioxo-2-thiazolidinone was studied as versatile core building block in the synthesis of new thiopyrano[2,3-d]thiazole derivatives relevant for medicinal chemistry purposes under hetero-Diels-Alder reaction conditions. Promising compounds (6, 10) were identified among synthesized series with high antitumor and moderate antiviral activity. [Supplementary materials are available for this article.
