    • It is to provide a novel optically active dibenzazepine derivative having a high utility value as an asymmetric phase-transfer catalyst. It is an optically active 6,7-dihydro-5H-dibenzo[c,e]azepine derivative represented by the following formula (1'), (wherein R represents a divalent organic group for cross-linking the 1 st position and the 11 th position; R 1 and R 2 are the same or different, and represent a hydrogen atom, halogen atom, or organic group, or R 1 and R 2 together represent a divalent organic group; R 3' and R 4' are the same or different and represent a monovalent organic group, or R 3' and R 4' together form an organic group that forms a cyclic structure comprising an onium nitrogen atom; Ar represents a monovalent organic group; * represents optical activity, i.e., that one axially asymmetric isomer is present in excess of the other axially asymmetric isomer with respect to a bond axis that constitutes the biphenyl structure of the compound; and X - represents a counter anion).
    • 本发明提供作为非对称相转移催化剂具有高利用价值的新型光学活性二苯并氮杂衍生物。 它是由下式(1')表示的旋光的6,7-二氢-5H-二苯并[c,e]氮杂卓衍生物,(其中R代表用于交联第1位和第11位的二价有机基团 ; R1和R2相同或不同,表示氢原子,卤素原子或有机基团,或者R1和R2一起表示二价有机基团; R3'和R4'相同或不同并且表示一价有机基团 ,或者R3'和R4'一起形成形成包含氮原子的环状结构的有机基团; Ar表示一价有机基团; *表示光学活性,即一个轴向不对称异构体轴向超过另一个 相对于构成化合物的联苯结构的键轴的不对称异构体;并且X-表示抗衡阴离子)。
