Title:
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/2005/073196
Kind Code:
A1
Abstract:
A compound of the following formula (I). This compound (I) can be produced by reacting a 1,1'-binaphthyl 2,2'-dimethylenebromide derivative which can be produced through a relatively small number of steps with an easily available secondary amine. The compound (I) is useful as a chiral phase-transfer catalyst.
