  • BETA-AMINO ACIDS AND METHODS AND INTERMEDIATES FOR MAKING SAME
    Publication number: 20120071664
    Abstract: Disclosed are ?-amino acids that are unsubstituted in the ? position; that are substituted in the ? position with an aryl group; that are substituted in the ? position with an aryl group; that bear two substituents in the ? position; and/or that are substituted in the ? and ? positions with groups which, together with the carbon atoms at the ? and ? positions, form a ring. Also disclosed are methods for making the above-mentioned ?-amino acids and other ?-amino acids which involve providing an ?,?-unsaturated imide; converting the ?,?-unsaturated imide to a 2-substituted-isoxazolidin-5-one; and converting the 2-substituted-isoxazolidin-5-one to a ?-amino acid.
    Type: Application
