The enhanced stability of the carbacephem nucleus over the correspondi
ng cephalosporin nucleus has allowed the synthesis of 7-arylglycyl-3-t
rifluoromethyl-carbacephems. These unique carbacephems possess broad s
pectrum activity and high stability to both plasmid and chromosomally
mediated beta-lactamases. (C) 1998 Elsevier Science Ltd. All rights re
