A facile and efficient procedure for the synthesis of substituted thiazole-2(3H)-thiones and thiazolidine-2-thiones by the reaction of primary amines, carbon disulfide, and nitroepoxides is described. By using secondary amines in this protocol, the corresponding dithiocarbamate-substituted phenyl-2-propanones were prepared in excellent yields. In addition, substituted thiazoles and 1-(alkylthio)-1
描述了一种通过伯胺,二硫化碳和硝基环氧化物反应合成取代的噻唑-2(3 H)-硫酮和噻唑烷-2-硫酮的简便有效的方法。通过在该方案中使用仲胺,可以以优异的产率制备相应的二硫代氨基甲酸酯取代的苯基-2-丙烷。另外,在S-烷基二硫代氨基甲酸酯和硝基环氧化物的反应中制备了取代的噻唑和1-(烷硫基)-1-苯基丙烷-2-酮。
