Frontispiece: Utilizing Palladium‐Stabilized Zwitterions for the Construction of N‐Heterocycles

Abstract

Pd catalysis provides a convenient method for the generation of zwitterionic intermediates that offer significant opportunities for the synthesis of functionalized heterocycles. The combination of electrophilic π‐allyl Pd fragments and C‐, N‐ and O‐centered nucleophiles allows these intermediates to react with readily available substrates to furnish a range of high value products with control of chemo‐, regio‐ and stereo‐selectivity.
