Synthesis and in vitro antibacterial activity of novel fluoroalkyl-substituted pyrazolyl oxazolidinones

A series of novel oxazolidinone derivatives bearing fluoroalkyl-substituted pyrazole as the C-ring structure were designed, synthesized and evaluated for their antibacterial activity against six Gram-positive bacterial pathogens. Most of the target compounds have good antibacterial activity. Especially, compounds 13f, 13i and 13l show excellent activity comparable to linezolid.
