Abstract A one‐pot facile synthesis of thiazole‐2(3H)‐thiones (4) has been achieved by hypervalent iodine oxidation of ketones (1) using [hydroxy(tosyloxy)iodo]benzene, followed by the treatment of the reaction mixture with dithiocarbamate salts (3). The intermediate α‐tosyloxyketones (2) have also been isolated and converted to the target compounds.
摘要 通过使用 [羟基(甲苯磺酰氧基)碘] 苯对酮(1)进行高价碘氧化,然后用反应混合物处理,实现了噻唑-2(3H)-硫酮(4)的一锅简便合成。二硫代氨基甲酸盐 (3)。中间体 α-甲苯磺酰氧基酮 (2) 也已被分离并转化为目标化合物。
