  Synthesis and Structure−Activity Relationship of (Lactamylvinyl)cephalosporins Exhibiting Activity against Staphylococci, Pneumococci, and Enterococci

  摘要：

  The synthesis and structure-activity relationships of a new class of vinylcephalosporins substituted with a lactamyl residue (1) are described. These compounds show excellent activity against enterococci and retain the broad spectrum activity of third-generation cephalosporins such as ceftriaxone.
