A series of 2-thiazolylamino-, 2-thiazolyloxy- and 2-thiazolylthio-arylacetic acid derivatives was prepared by condensation of thioamides with halo-acetals according to Hantzsch's method, and thioamides having the α-methylarylacetic acid moiety were conveniently obtained from haloaromatic nitro compounds by a combination of known methods. In the model reaction of O-phenyl thiocarbamate (XVIII) with chloro-diethylacetal, isolation of intermediates such as acyclic halo-compound (XIX) and 4-ethoxy-2-phenoxy-2-thiazoline (XX) clarified the reaction path for the formation of 2-phenoxythiazole (XXI). The analgesic and anti-inflammatory effects of the compounds studied were evaluated by using the acetic acid-induced writhing method in mice and the rat carrageenin paw edema method, respectively. 2- [4- (2-Thiazolyloxy) phenyl] propionic acid (XIVa) had the most favorable therapeutic ratio between activity and toxicity (in mice).
Green and efficient synthesis of thioureas, ureas, primary <i>O</i>-thiocarbamates, and carbamates in deep eutectic solvent/catalyst systems using thiourea and urea
developed for the direct preparation of various primary O-thiocarbamates/carbamates as well as monosubstituted thioureas/ureas by using thiourea/urea as biocompatible thiocarbonyl (carbonyl) sources. This procedure used choline chloride/tin(II) chloride [ChCl][SnCl2]2 with a dual role as a green catalyst and reaction medium to afford the desired products in moderate to excellent yields. Moreover, the DES can
通过使用硫脲/尿素作为生物相容性硫代羰基(羰基)源,开发了一种有效且通用的催化方法,用于直接制备各种伯O-硫代氨基甲酸酯/氨基甲酸酯以及单取代硫脲/脲。该过程使用氯化胆碱/氯化锡 ( II ) [ChCl][SnCl 2 ] 2,具有作为绿色催化剂和反应介质的双重作用,以中等至极好的收率提供所需产物。此外,DES 可以很容易地回收和重复使用七个循环,而其活性没有显着损失。此外,该方法在大规模合成所需产物方面表现出非常好的性能。
