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 (&#b1;)-5-(acetamidomethyl)-3-[4-(3-pyridyl)-3,5-difiuorophenyl]-2-oxazolid inone.Field of SearchUnsaturated ring attached directly to the six-membered hetero ring by nonionic bondingAdditional hetero ring containing Unsaturated carbocyclic ring attached directly to the quinoline ring system by nonionic bonding (e.g., quinophthalones, etc.) Ring nitrogen in the additional hetero ring (e.g., oxazole, etc.) Six-membered ring consisting of one nitrogen and five carbons (e.g., pyridine, etc.) Quinoline or isoquinoline (including hydrogenated) |
