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