The catalytic enantioselective conjugate addition reaction of α-nitroacetate to α,β-unsaturated enones promoted by chiral bifunctional organocatalysts is described. The treatment of α-nitroacetate to α,β-unsaturated enones afforded the corresponding Michael adducts with high enantioselectivity. The conjugate addition adducts are easily converted to chiral γ-nitro ketones and δ-keto esters.
描述了由手性双功能有机催化剂促进的 α-硝基乙酸酯与 α,β-不饱和烯酮的催化对映选择性共轭加成反应。将 α-硝基乙酸酯处理成 α,β-不饱和烯酮得到了具有高对映选择性的相应迈克尔加合物。共轭加成物很容易转化为手性 γ-硝基酮和 δ-酮酯。
