  • Process for the preparation of oxazolidinones and method of use thereof
    Publication number: 20070265451
    Abstract: A process for preparing N-(substituted)-C-(substituted methyl)-oxazolidinones, C-(substituted methyl)-oxazolidinones, and N-(substituted)-C-(substituted methyl)-oxazolidinones, preferably chiral, from optically active C-(protected oxymethyl)-oxazolidinones is described. The process can be used to produce combinatorial libraries of the above substituted oxazolidinones in a two or three step reaction comprising a plurality of reagents differing in numbers of carbons or particular substituted oxazolidinones. A number of substituted oxazolidinones produced using the above process have been discovered to have antimicrobial activity.
