  摘要：

  描述了α-硝基乙酸与由手性双官能有机催化剂促进的α，β-不饱和酮的催化对映选择性共轭加成反应。在水相反应条件下将α-硝基乙酸酯处理为α，β-不饱和酮，得到具有高对映选择性的相应的迈克尔加合物。共轭加合物容易转化为手性δ-酮硝基烷和δ-酮酯。

  Based on different chiral diamine skeletons, a series of bifunctional primary amine-thiophosphoramides were synthesized and screened as the catalysts for the asymmetric Michael addition of acetone to both aromatic and aliphatic nitroolefins. Under the catalysis of a thiophosphoramide derived from 1,2-diphenylethane-1,2-diamine, the corresponding adducts were obtained in high yields (up to >99%) with

  highly diastereoselective and enantioselective Michael addition of cyclohexanone, acetone and other ketones to nitroolefins was developed by the use of an amine organocatalyst based on bispidine. Additionally, a theoretical study of transition structures revealed that this bispidine-based primary-secondary amine catalyst could serve through an enamine intermediate and H-bond interaction, which was
