A convenient four-step preparation route to novel 7-chloro-imidazo[2,1-b][1,3]thiazin-5-ones is presented, starting from methyl phenylglyoxylate. A unique feature of this synthesis is a heterocyclization strategy, in which a halogen atom is introduced already during the ring closure. 7-Chloro-6-phenyl-imidazothiazinones with a broad range of various substituents in the phenyl and imidazole moieties
从苯乙醛酸甲酯开始,提出了一种方便的四步制备路线,用于制备新型7-氯-咪唑并[2,1- b ] [1,3]噻嗪-5-酮。该合成的独特特征是杂环化策略,其中在闭环过程中已经引入了卤素原子。通过该方法可获得在苯基和咪唑部分中具有广泛的各种取代基的7-氯-6-苯基-咪唑并噻嗪酮,以及不同的氯化三唑并噻嗪酮。在亲核取代反应中,氯官能团很容易被氨基,烷氧基和芳硫基以及氟原子取代。
1,4,5-Trialkyl Imidazole System Anti-inflammatory Properties of New Substituted Derivatives.
In an investigation of the anti-inflammatoryproperties of five-membered ring nitrogen-containing heterocyclic compounds, two series of derivatives of imidazole were prepared by altering the sites of substitution and by joining aliphatic chains to the nitrogen atom in the 1 position of the imidazole ring. Some of them were more potent inhibitors of carrageenan-induced edema than indomethacin. An electron

ketenimines and following a 1,4‐diazabicyclo[2.2.2]octane (DABCO) catalyzed aza‐Mannich type reaction with various 2‐mercaptoimidazoles for the synthesis of 1,3‐bis(β‐aminoacrylate)‐substituted 2‐mercaptoimidazole derivatives with structural diversity. In addition, the use of 1H‐benzo[d]imidazol‐2‐ol as the reaction partner also allowed the formation of 1,3‐bis(β‐aminoacrylate)‐substituted 2‐benzimidazolinone
我们开发了钯催化的异氰酸酯与α-重氮乙酸酯的交叉偶联反应,以形成活性酮亚胺,然后在1,4-二氮杂双环[2.2.2]辛烷(DABCO)催化下的氮杂-曼尼希型反应与各种2-巯基咪唑反应制得1,3-双(β-氨基丙烯酸酯)取代的2-巯基咪唑衍生物的合成,具有结构多样性。此外,使用1 H-苯并[ d ]咪唑-2-醇作为反应伙伴还可以形成1,3-双(β-氨基丙烯酸酯)取代的2-苯并咪唑啉酮衍生物,产率适中(34-52 %)。在aza-Mannich反应中,区域选择性N攻击而非S攻击或O观察到了酮亚胺的亲电子中心碳的攻击。此串联序列是有效的,因为在一个锅中连续创建了两个C = C和两个CN键。
