Title:
METHOD FOR SYNTHESIZING BINAPHTHYLDIAMINE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2015/019928
Kind Code:
A1
Abstract:
The present invention relates to a novel synthesis method that is capable of producing an optically active binaphthyldiamine derivative, under conditions whereby the binaphthyldiamine derivative can be produced more safely and efficiently, the binaphthyldiamine derivative being useful as a raw material for synthesizing a catalyst used in a variety of asymmetric syntheses. The present invention provides a method for producing an optically active binaphthyldiamine derivative (compound [V]) by means of thermal rearrangement from an optically active binaphthyldicarboxylic acid derivative (compound [VII]) (in the formulae, the reference numerals are as defined in the present specification).
