摘要:
The present invention discloses novel substituted aryl- and heteroarylphenyloxazolidinones which are useful as anti-bacterial agents. More specifically, the substituted aryl- and heteroarylphenyloxazolidinones of the invention are characterized by oxazolidinones having an aryl or heteroaryl group at the p-position of the 3-phenyl ring and additional substitutions at the m-position(s) of the 3-phenyl ring. A compound representative of this new class of oxazolidinones is (.+-.)-5-(acetamidomethyl)-3-�4-(3-pyridyl)-3,5-difluorophenyl!-2-oxazolidinone.
