title: Synthesis and biological activity of C-3' ortho dihydroxyphthalimido cephalosporins.
abstract: A series of C-3' ortho dihydroxyphthalimido cephalosporins 3-7 has been prepared by reaction of C-3' aminomethyl cephalosporin 41 with the corresponding N-carboethoxyphthalimides 23-25, 37, 38. These new cephalosporins exhibit excellent in vitro Gram-negative activities, including Pseudomonas aeruginosa, excellent beta-lactamases stability and pharmacokinetics equivalent or better than ceftriaxone.
