methodology for kineticresolution of axiallychiral2-amino-1,1′-biaryl compounds as useful chiral building blocks was developed by means of binaphthyl-modified chiral quaternary ammonium salt-catalyzed N-allylations under phase-transfer conditions. The catalyst structure and reaction conditions were carefully optimized to achieve the highly selective kineticresolutions. Various types of 2-amino-1,1′-biaryls
