    名称:
    Chemistry of oxaziridines. 18. Synthesis and enantioselective oxidations of the [(8,8-dihalocamphoryl)sulfonyl]oxaziridines
    摘要:
    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.

    The diastereoselective reduction of both cyclic and acyclic camphor sulfonylimines was investigated. With cyclic camphor sulfonylimines 1, reduction using NaBH4 in methanol afforded the corresponding camphorsultarns 2 in 92-95% yield as single diastereomers with the exception of Ic where debromination occurred prior to reduction. For the large scale preparation of camphorsultam la and its derivatives, important chiral auxiliaries in asymmetric synthesis, reduction with NaBH4 is the reagent of choice. Reduction of acyclic camphor sulfonylimines 7 to camphorsulfonamides 8 with the bulky reducing reagent, LiAl(OBu-i)(3)H afforded the highest de's (>90% de) and yields 90-95%.
  • Asymmetric Fluorination of Enolates with Nonracemic <i>N</i>-Fluoro-2,10-Camphorsultams

    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.
