C−C Bond-Forming Reactions via Pd-Mediated Decarboxylative α-Imino Anion Generation

Abstract

Alpha-imino anions are generated under neutral reaction conditions via a Pd-mediated decarboxylation of allyl diphenylglycinate imines with concomitant formation of a pi-allylpalladium species. The resulting delocalized anion can attack the pi-allyl-Pd(II) species or be intercepted by aldehydes to afford homoallylic amines or protected 1,2-amino alcohols, respectively.
