  • Title: Asymmetric synthesis of substituted tropinones using the intramolecular mannich cyclization reaction and acyclic N-sulfinyl beta-amino ketone ketals.
    Author: Davis FA, Theddu N, Gaspari PM.
    Journal: Org Lett; 2009 Apr 02; 11(7):1647-50. PubMed ID: 19278245.
    Abstract:
    Sulfinimine-derived, enantiopure N-sulfinyl beta-amino ketone ketals on hydrolysis give dehydropyrrolidine ketones that on treatment with (Boc)(2)O/DMAP afford substituted tropinones in good yield.
