Outline of Final Research Achievements |
Binaphthyl groups with axial chirality compose many chiral ligands (ex. BINAP) used in asymmetric synthesis. Preparation of monoclonal antibodies (MABs) specific for each optical isomer is thought to be appropriate to realize convenient chiral separation and asymmetric catalytic system. We obtained MABs specific for one of optical isomers of binaphthyl derivative (BN) by immunization with racemic mixture. One of the chiral isomers of BN could be separated with high e.e. by a simple procedure using the corresponding mAbs. MABs which can bind not only rhodium complex but also palladium complex were obtained. The catalytic activity of the complex between monoclonal antibody with the palladium catalyst was examined. Allylic amination reaction was found to be catalyzed with high stereoselectivity by utilizing the MAB-palladium complex.
