oic acid. A highly enantioselective Michael addition of aromatic ketones to α,β,γ,δ-unsaturated nitro compounds is described. In the presence of a chiral primary amine-thiourea based on dehydroabietic amine, γ-nitro ketones were obtained in excellent enantioselectivities (up to 95% ee) with up to 95% yield. In addition, this methodology has been successfully applied in the asymmetric synthesis of chiral
摘要 描述了芳族酮对α,β,γ,δ-不饱和硝基化合物的高度对映选择性迈克尔加成。在基于脱氢松香胺的手性伯胺-硫脲的存在下,以优异的对映选择性(高达95%ee)获得了γ-硝基酮,产率高达95%。另外,该方法已成功地用于手性3-(氨基甲基)-5-苯基戊酸的不对称合成。 描述了芳族酮对α,β,γ,δ-不饱和硝基化合物的高度对映选择性迈克尔加成。在基于脱氢松香胺的手性伯胺-硫脲的存在下,以优异的对映选择性(高达95%ee)获得了γ-硝基酮,产率高达95%。另外,该方法已成功地用于手性3-(氨基甲基)-5-苯基戊酸的不对称合成。
