The present review is mainly focused upon the use of C-substituted oxazolidin-2-ones as chiral auxiliaries in the stereocontrolled C-C and C-X (X = hetero atom) bond formation.The recent progress in the stereoselective alkylation, cycloaddition and aldol reaction, as well as in the 1,4-coniugate addition, in [2+2]photocycloaddition, in Lewis acid promoted free-radical copolymerization reactions are discussed. Emerging new applications of the oxazolidin-2-one nucleus, such as building blocks in the design and preparation of foldamers or as organocatalyst in enantioselective epoxidation reactions, will be also discussed.

This review provides an overview of twenty years of pioneering work (from 1985 to 2005) of our research group in the preparation and application of enantioselective packing materials for HPLC. After a brief introduction to the rational design of a new chiral stationary phase, a detailed presentation in chronological order of appearance in the literature is given of the currently developed repertoire of chiral stationary phases and their typical applications. Emphasis is placed on the different synthetic strategies exploited to obtain highly efficient, stable, and versatile chiral stationary phases.
