We herein report a general, practical, and highly efficient method for asymmetricsynthesis of a wide range of chiral vicinal diamines via reductive coupling of imines templated by chiral diboron. The protocol features high enantioselectivity and stereospecificity, mild reaction conditions, simple operating procedures, use of readily available starting materials, and a broad substrate scope. The method

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.
