    • [Problem] To provide a production method of optically active epoxy compound, and a complex used for the production method and a production method of the complex. [Means for solving the problem] The skeleton that is necessary for expressing a high catalyst activity of optically active titanium salan complex of formulae (1) and (1′) and the substituent that is useful therefor and the position of the substituent are identified, and it is found that optically active epoxy compounds can be produced with a high enantioselectivity and a high chemical yield compared with a case where the prior optically active titanium salan complex is used. The production method comprises subjecting a prochiral compound (formula (4), (5) or (6)) having carbon-carbon double bond in the molecule to asymmetric epoxidation to produce an optically active epoxy compound (formula (7), (8) or (9)). The present invention relates also to a complex used for the production method and a production method of the complex.
    • [问题]提供光学活性环氧化合物的制备方法和复合体的制造方法和制造方法中使用的复合体。 [解决问题的手段]鉴定表达式(1)和(1')的光学活性钛salan复合物和其有用的取代基的高催化剂活性所必需的骨架和取代基的位置, 并且发现与使用现有的光学活性钛砂复合物的情况相比,可以以高对映选择性和高化学产率制备光学活性环氧化合物。 该制造方法包括使分子中具有碳 - 碳双键的前手性化合物(式(4),(5)或(6))进行不对称环氧化反应,得到光学活性环氧化合物(式(7),(8) 或(9))。 本发明还涉及复合物的制造方法和制造方法中使用的复合体。
