<p>Novel optically active dibenzazepine derivatives having high utility value as chiral phase-transfer catalyst, more specifically, optically active 6,7-dihydro-5H-dibenz- [c,e]azepine derivatives represented by general formula (1') [wherein R is a divalent organic bridging group for joining the 1- and 11-positions; R1 and R2 may be the same or different and are each hydrogen, halogeno, or an organic group, or R1 and R2 may together represent an divalent organic group; R3' and R4' may be the same or different and are each a monovalent organic group, or R3' and R4' may together represent a cyclic organic group containing the onium nitrogen atom; Ar is a monovalent organic group; * represents optical activity, that is, an excess of one axially chiral isomer over the other axially chiral isomer, both isomers being due to the bond axis constituting the biphenyl structure of the derivative; and X- is a counter anion].</p> |
