A novel bis-phosphate compound is provided which can be applied to a wide range of reactive substrates and reactions as an asymmetric reaction catalyst and can realize an asymmetric reaction affording a high yield and a high enantiomeric excess. The bis-phosphate compound has a tetraaryl skeleton represented by General Formula (1). In an asymmetric reaction, an amidodiene and an unsaturated aldehyde compound are reacted with each other in the presence of the optically active bis-phosphate compound to give an optically active amidoaldehyde. The invention allows a reaction such as an asymmetric Diels-Alder reaction to proceed efficiently, which has been difficult with conventional mono-phosphate compounds. Thus, the invention enables an industrially feasible method for the production of optically active amidoaldehydes, optically active β-amino acid derivatives, optically active diamine compounds, optically active pyrrolidine derivatives and optically active dihydropyran derivatives which are useful as products such as medicines, agricultural chemicals and chemical products as well as synthesis intermediates for such products.
提供了一种新型的双磷酸盐化合物,可应用于广泛的反应底物和反应作为不对称反应催化剂,并且可以实现产率高和对映体过量高的不对称反应。该双磷酸盐化合物具有由通用式(1)表示的四芳基骨架。在不对称反应中,存在光学活性的双磷酸盐化合物的情况下,通过使酰胺二烯和不饱和醛化合物相互反应,得到光学活性的酰胺醛。该发明使得像不对称Diels-Alder反应这样的反应能够高效进行,而传统的单磷酸盐化合物很难实现。因此,该发明实现了一种工业上可行的方法,用于生产用作药品、农药和化工产品以及用于这些产品的合成中间体的光学活性酰胺醛、光学活性β-氨基酸衍生物、光学活性二胺化合物、光学活性吡咯烷衍生物和光学活性二氢吡喃衍生物。
