  • Publication number: 20140303385
    Abstract: The present invention provides processes for the production of chiral compounds in a stereoisomeric excess. The present processes involve reacting a hydrometallated alkene compound with a compound comprising a conjugated-bond system under conditions such that the compounds undergo an asymmetric 1,4- or 1,6-conjugate addition reaction, generating a chiral compound in a stereoisomeric excess. The reaction is performed in the presence of a metal catalyst, which catalyst preferably comprises a non-racemic chiral ligand.

  • Patent number: 5319115
    Abstract: This invention provides a simplified method for converting pregnan-3,20-dione compounds to 3.alpha.-hydroxy,3.beta.-substituted-pregnanes. By selective use of reagents the unprotected dione is converted chemoselectively and diastereoselectively into a 3(R)-pregnan-3-spiro-2'oxirane-20-one intermediate. This intermediate can then be converted regioselectively by a second set of reactions to the 3.alpha.-hydroxy,3.beta.-substituted-20-one form, which can be further modified at the 20-keto position.Through this method, each ketone group is independently treated. By modifying the ketones one at a time, one can obtain the desired stereo-specificity at each site.
