摘要

Antibacterial compounds have the formula CHEM wherein R1 is hydrogen, a pharmaceutically acceptable cation, or alkyl; A is CH, CF, CCl or N; Y is alkyl, haloalkyl, cyclopropyl, vinyl, methoxy, N-methylamino, p-fluorophenyl, p-hydroxyphenyl or p-aminophenyl; or A is carbon and is taken together with Y and the carbon and nitrogen to which A and Y are attached to form a five to seven membered ring which is optionally substituted; and R2 is a bridged-diazabicycloalkyl group.
