4-(Phenylsulfonylthio)-2-azetidinones have been prepared conveniently by the reaction of 4-(2-benzothiazolyldithio)-2-azetidinones with 2-benzothiazolyl benzenethiosulfonates. A combination of this reaction with the electrolytic cross-coupling of bis(benzothiazolyl) disulfide and ammonium benzenesulfinate can establish a recycling system, in which S-(2-benzothiazolyl) benzenethiosulfonate is regenerated to play a critical role in penicillin–cephalosporin conversions.
4-(苯磺酰硫基)-2-氮杂环丁酮已通过4-(2-苯并噻唑基二硫代)-2-氮杂环丁酮与2-苯并噻唑基苯硫代磺酸盐的反应方便地制备。该反应与双(苯并噻唑基)二硫化物和苯亚磺酸铵的电解交叉偶联相结合,可以建立一个回收系统,其中S-(2-苯并噻唑基)苯硫磺酸盐被再生,在青霉素-头孢菌素转化中发挥关键作用。
