IRIDOIDS : ENANTIOSELECTIVE SYNTHESIS OF LOGANIN VIA AN ASYMMETRIC DIELS-ALDER REACTION

Starting from (-)-camphor-10-sulfonic acid (5) the crystalline sultam 9 was readily prepared.TiCl4-mediated Diels-Alder addition of the N-crotonyl sultam 11 to cyclopentadiene, crystallization of the resulrting adduct 12 and subsequent reduction gave virtually pure (1S, 4R,5R, 6S)-1 together with recovered auxiliary 9.The loganin precursor 1 was transformed into norbonanone 20, which upon Baeyer-Villiger oxidation led to the suitably substituted cyclopentane 22 from which 1-B-O-methyl loganin aglucone (2) was readily available.

Progress toward the total synthesis of callipeltin A (I): Asymmetric synthesis of (3S,4R)-3,4-dimethylglutamine

(equation presented) During the total synthesis of the novel cyclic depsipeptide callipeltin A (1), the unit (3S,4R)-3,4-dimethylglutamine, was successfully synthesized by asymmetric Michael addition and subsequent electrophilic azidation. The key feature of this approach is the generation of three adjacent stereogenic centers using the same camphorsultam chiral auxiliary.

Chemistry of Oxaziridines. 18. Synthesis and Enantioselective Oxidations of the <(8,8-Dihalocamphoryl)sulfonyl>oxaziridines

The synthesis and enantioselective oxidations of <(8,8-dihalocamphoryl)sulfonyl>oxaziridines 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 percent) and for the hydroxylation of enolates (often better than 95 percent ee).In general the molecular recognition is predicted and explained in terms of minimization of nonbonded steric interactions in 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 percent vs 22 percent ee.

Asymmetric synthesis of sultams and sulfonamides via diastereoselective reduction of N-sulfonylimines

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 camphorsultams 2 in 92-95% yield as single diastereomers with the exception of 1c where debromination occurred prior to reduction. For the large scale preparation of camphorsultam 1a 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)3H afforded the highest de’s (>90% de) and yields 90-95%.
