Oxazolidin-2-one ring, a popular framework in synthetic organic chemistry part 2. Applications and modifications

摘要

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-conjugate 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.
