  An efficient method for the α-chlorination of ketones under basic conditions is described using methyl chlorosulfate. Its applicability for the chlorination of other functional groups has also been studied and it is equally useful for the synthesis of α-chloroesters and amides. Methyl chlorosulfate is described for the first time as a positive chlorine source. Some aldol reactions which occur during

  new protocol for the direct two-electron oxidative Umpolung of alkali halide salts is reported. This procedure, relying on the use of a commercially available sulfoxide as the oxidant, allows the electrophilic halogenation of carbonyl compounds as well as halolactonisation reactions to proceed from the corresponding sodium salts, at room temperature and under mild conditions.

  The asymmetric "electrophilic" fluorination of tertiary enolates by nonracemic N-fluoro-2,10-camphorsultams 3 affords quaternary alpha-fluoro carbonyl compounds in modest yield and ee. The highest asymmetric induction was observed for the fluorination of the sodium enolate of 2-methyl-1-tetralone (8a) by (-)-N-fluoro-2,10-(3,3-dichlorocamphorsultam) (3b) to give (S)-(+)-2-fluoro-2-methyl-1-tetralone (9a) in 70% ee. The absolute configuration was established by X-ray crystallography of the corresponding diastereomeric beta-hydroxy sulfoximine prepared from (+/-)-9a and the Johnson reagent. The asymmetric induction exhibited by 3 is opposite to that of the closely related enolate hydroxylation reagents nonracemic (camphorylsulfonyl)oxaziridines 4. The N-fluoro sultams 3 were prepared by fluorination (10% F-2/N-2) of the corresponding sultams 5.

  The synthesis and enantioselective oxidations of [(8,8-dihalocamphoryl)sulfonyl]oxaziridines [8,8-dichloro-1,7,7-trimethyl-2'-(phenylsulfonyl)spiro[bicyclo[2.2.1]heptane-2,3'-oxazinidine]] 13 are reported. These reagents are prepared in two steps from the (camphorylsulfonyl)imine 4 by treatment of the corresponding azaenolate with electrophilic halogen sources followed by biphasic oxidation of the resulting dihalo imine 6-9 with m-CPBA/K2CO3. Of these oxaziridines the dichloro reagent 13b, available on a multigram scale, affords the highest enantioselectivities for the asymmetric oxidation of sulfides to sulfoxides (42-74%) and for the hydroxylation of enolates (often better than 95% ee). In general the molecular recognition is predicted and explained in terms of minimization of nonbonded steric interactions the transition states. For the asymmetric oxidation of sulfides to sulfoxides, secondary electronic factors related to the polarity of the sulfide and oxaziridine also play a role. Definitive evidence for chelation of the metal enolate with the C-X bond in 13 is not found. The molecular recognition is interpreted in terms of the higher reactivity of the reagents and an active-site structure which is sterically complementary with the enolate. For the asymmetric hydroxylation of the Z- and E-enolates of propiophenone (16a), the Z-enolate exhibits much higher stereoselectivity than the E-enolate: >95% vs 22% ee.
