The Chemistry of N-Sulfonyl Enamines
Hegedus, Louis S.,Holden, Michael S.
, p. 1171 - 1174 (2007/10/02)
N-Tosyl enamines are available in multigram quantities using a palladium(II)-catalyzed cyclization process.This unusual class of compounds has limited nucleophilic character at the β-position, undergoing protonation and halogenation by N-halosuccinimides.
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
