Abstract

This invention provides compositions which are 1,3-oxazinan-2-one compounds of formulae (I) and (II), and oxazolidinone compounds of formula (III): wherein R is a hydrocarbyl group, a heterocyclic group, a hydrocarbyl group having at least one substituent, or a heterocyclic group having at least one hydrocarbyl substituent, wherein the substituent on the hydrocarbyl group or heterocyclic group is selected from the group consisting of a heterocyclic group, an azo group, a cyano group, a nitro group, a fluoro group, a chloro group, a bromo group, an alkoxy group having up to 15 carbon atoms, and a hydrocarbyl group having up to 15 carbon atoms; and R' and R″ are each independently hydrogen, an alkyl group, an aryl group, a methylaryl group, a carbonyl group, a hydrocarbylamido group, a sulfonyl group, a sulfonamoyl group, a heterocyclic group, a heterocyclic group having at least one substituent, or an aryl group or methylaryl group having at least one substituent, where the substituent on the heterocyclic group, aryl group, or methylaryl group is selected from the group consisting of a heterocyclic group, an azo group, a cyano group, a nitro group, a fluoro group, a chloro group, a bromo group, an alkoxy group having up to 15 carbon atoms, and a hydrocarbyl group having up to 15 carbon atoms. For the oxazolidinone compound of formula (HI), there is a proviso that when one of R′ or R″ is a (3-fluoro)-(4-morpholinyl)-phenyl group, the other of R′ or R″ is not an acetamido group.
