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%.
