The synthesis of new 7α-methoxy-7-(2-substituted thio) acetamido derivatives of cephalosporin by nucleophilic displacement of the halogen atom of 7β-(2-halogenoacetamido)-7-methoxy cephalosporanic acid derivatives was described. The in vitro antimicrobial activities were also described.
通过亲核置换 7β-(2-卤代乙酰氨基)-7-甲氧基头孢烷酸衍生物的卤原子,合成了新的 7α-甲氧基-7-(2-取代硫代)乙酰氨基头孢衍生物。还描述了体外抗菌活性。
