OPTICALLY ACTIVE QUATERNARY AMMONIUM SALT HAVING AXIAL ASYMMETRY AND PROCESS FOR PRODUCING &agr -AMINO ACID AND DERIVATIVE THEREOF WITH THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/104226
Kind Code:
A1
Abstract:
A chiral phase-transfer catalyst represented by the following formula (I). (I) The compound (I) can be produced by reacting 1,1'-biphenyl 2,2'-dimethylenebromide derivative which can be produced through a relatively small number of steps with an easily available secondary amine.
