1,1-Dioxo-7α-methoxy-3-methyl-Î3-cephem-4-yl phenyl ketone, a valuable precursor of potent HLE inhibitors, was obtained in an efficient way starting from 7α-methoxy-3-methyl-Î3-cephem-4-carboxylic acid. By employing the same methodology a variety of 1,1-dioxocephem-4-yl aryl ketones were prepared.
1,1-二氧代-7α-甲氧基-3-甲基-3-头孢-4-基苯基甲酮是从7α-甲氧基-3-甲基-3-头孢-4-羧酸出发,以有效的方式获得的强效HLE抑制剂的重要前体。通过采用相同的方法,制备了多种1,1-二氧代头孢-4-基芳基酮。
