头孢雷特是临床中常用的第二代头孢类抗生素,其临床应用前景十分看好。2-氨甲基苯乙酸是生产头孢雷特的重要中间体,由于该化合物中同时存在氨基和羧基两个活性集团,因此,在生产中需要先将氨基进行保护,以便羧基进行下一步反应。 Cefradile is the second-generation cephalosporin commonly used in clinical practice, its clinical application prospects are very good. 2-Aminomethyl phenylacetic acid is an important intermediate for the production of ceforanile. Since both the amino and carboxyl groups exist in the compound, the amino group needs to be protected in order to allow the carboxyl group to undergo the next reaction.
