title = "Catalytic iron-mediated ene carbocyclizations of trienes: Investigations into the stereoselective formation of some bicyclic lactams and amines.",
abstract = "Certain bicyclic ring systems (i.e., indolizidine and quinolizidine ring systems) are constructed in a stereoselective fashion using an iron-catalyzed carbocyclization. It is noteworthy that the reduced iron catalyst tolerates triene substrates containing a basic nitrogen and that the chemical efficiency and the degree of 1,3-stereoinduction are dramatically influenced by the nature of the substrate (amine versus amide) and the nature of the ligand (2,2′-bipyridine versus bisoxazoline) employed in the iron catalyst system.",
