Abstract
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 1position and the 11position; Rand Rare the same or different, and represent a hydrogen atom, halogen atom, or organic group, or Rand Rtogether represent a divalent organic group; Rand Rare the same or different and represent a monovalent organic group, or Rand Rtogether 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 Xrepresents a counter anion).
