  • Title: Nitrogen heterocycles via palladium-catalyzed carbocyclization. Formal synthesis of (+)-alpha-allokainic acid.
    Author: Cook GR, Sun L.
    Journal: Org Lett; 2004 Jul 08; 6(14):2481-4. PubMed ID: 15228309.
    Abstract:
    [reaction: see text] The Pd-catalyzed carbocyclization of ketoamides was investigated and found to be highly dependent on the phosphine ligand as well as the presence of coordinating counterions. Nitrogen heterocycles were formed without erosion of the stereochemical integrity. The utility of the lactam products was demonstrated by the formal synthesis of (+)-alpha-allokainic acid.
