Abstract: The reagentantrolled asymmetric oxidation of tri-and tetrasubstituted ketone enolate anions 4 and 8 by enantiomerically pure (camphorylsulfony1) oxaziridine 2 has been investigated. The stereoselectivities for oxidation of trisubstituted enolates 4a-d are good to excellent, 60-95% ee, while those for tetrasubstituted enolates 4e and 8 are lower: Le., 21-30% ee. Isolated chemical yields for both types of enolate anions are good to ...
