3-Trifluoromethylcarbacephems: Synthesis of broad spectrum antibacterial compounds

The enhanced stability of the carbacephem nucleus over the corresponding cephalosporin nucleus has allowed the synthesis of 7-arylglycyl-3- trifluoromethyl-carbacephems. These unique carbacephems possess broad spectrum activity and high stability to both
