, p. 5440 - 5452 (2007/10/03)
The synthesis of dihydropyrroles, pyrroles, and indoles through [3-atom + 2-atom] combination of ethyl or aryl tosylamide anions with phenyl(propynyl)iodonium triflate, and the base-mediated intramolecular bicyclization of alkynyliodonium-bearing tosylamide or tosylimide substrates to furnish bicyclic and tricyclic tosylenamide (-enimide) products, is described. A detailed discussion of the scope, limitations, byproduct formation, and the basis for observed diastereoselectivity is presented.
Palladium-Catalyzed Cyclization of ω-Olefinic Tosamides. Synthesis of Nonaromatic Nitrogen Heterocycles
Hegedus, Louis S.,McKearin, James M.
, p. 2444 - 2451 (2007/10/02)
The cyclization of aliphatic amino olefins to nonaromatic nitrogen heterocycles nas been accomplished by conversion of the amine to the corresponding p-toluenesulfonamide, followed by Pd(II)-catalyzed intramolecular amination of the olefin.The resulting t
