  Asymmetric Henry reaction catalyzed by chiral secondary diamine-copper(II) complexes

  摘要：

  The enantioselective Henry reaction was efficiently carried out under mild reaction conditions in 96% ethanol. The chiral C-2-symmetric, secondary bisamines based on the 1,2-diaminocyclohexane framework and copper(II) acetate were found to promote the asymmetric nitroaldol reaction. Aromatic and aliphatic aldehydes were reacted with nitromethane to provide the corresponding beta-nitroalcohols in very good yields and enantioselectivities up to 94%. (C) 2008 Elsevier Ltd.

  A series of N,N′-dialkylated derivatives of (1R,2R)-cyclohexane-1,2-diamine were synthesized, and a new approach to the one-pot preparation of this type of amine was demonstrated. The prepared diamines were used as organocatalysts for the two-step synthesis of α-hydroxy γ-keto esters from arenes, chlorooxoacetates, and ketones; they were also used as chiral ligands for Meervein–Ponndorf–Verley reductions
