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.

Ascorbic acid (Vitamin C) (9) is shown to be a useful, inexpensive chiral starting material for natural products synthesis. It is converted in high yield via two synthetic operations into (R)-glycerol acetonide (7), the more inaccessible enantiomer of glycerol acetonide. Since D-(R)-glyceraldehydeacetonide (4) and the corresponding alcohol 1 have been used in many total syntheses of a wide variety
