Abstract
There is provided a method for producing an optically active salicylaldimine copper complex, which method is characterized in that an optically active amino alcohol compound represented by the following formula (1) is reacted with copper hydroxide (II) in an organic solvent. 1 wherein R1 and R2 which are the same or different, each represent lower alkyl groups and the like which may be substituted, X1 and X2 which are the same or different, each represent a hydrogen atom, lower alkyl groups and the like, and the symbol * designates an asymmetric carbon atom.
Claims5
A method for producing an optically active salicylaldimine copper complex, comprising reacting a copper hydroxide (II) with an optically active salicylaldimine compound of formula (1):
- 5
- wherein R1 and R2 are the same or different and independently represent a substituted or unsubstituted lower alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group,
- X1 and X2 are the same or different and independently represent a hydrogen atom, a substituted or unsubstituted lower alkyl group, a lower alkoxy group, a nitro group, a lower alkoxycarbonyl group or a halogen atom, and
- the symbol * designates an asymmetric carbon atom,
- provided that X1 and X2 on adjacent carbon atoms, together with the carbon atom to which they are boded form a benzene ring, in an organic solvent.
