  • Publication number: 20070276145
    Abstract: A method of synthesizing a chiral compound having a quaternary carbon atom bearing diastereotopic groups from (a) a nitroolefin and (b) an ?-substituted ?-dicarbonyl or an equivalent compound having an acidic C—H moiety compound is disclosed. A subsequent intramolecular reaction between one of the substituents comprising the stereogenic carbon atom and one of the diastereotopic groups comprising the quaternary carbon atom creates a new compound having two contiguous stereogenic centers, one of which is quaternary, with control over the relative stereochemistry.
