ABSTRACT:
It is made possible to carry out asymmetric organic syntheses such as an asymmetric imono aldol reaction etc. catalytically with high reactivity and selectivity. An asymmetric zirconium catalyst having a structure that zirconium (IV) being an active central atom of the catalyst and being bonded via oxygen atoms to two molecules of optically active binaphthyl groups is proposed.
