An enantioselective Henry reaction was efficiently carried out under mild reaction conditions in the presence of catalytic 9-epi and natural Cinchonaalkaloids and copper (II) acetate. The best catalytic performance was observed for native quinine (12 mol %) and Cu(OAc)2 (10 mol %). Aromatic and aliphatic aldehydes with nitromethane and its α-substituted derivatives provided the corresponding β-nitroalcohols
