Abstract:
     A chiral ligand compound-chiral dibenzo [a,c] cycloheptadiene dioxazoline ligand is prepared from 6,6-disubstituted dibenzo [a,c]-1,3-cycloheptadiene or its derivative through hydrolyzing to become acid, and reaction on chiral alkamine. The resultant compound has high catalyst performance, so it can be compleved with transition metal to become chiral catalyst used for asymmetrical cyclopropane reaction, asymmetrical allyl alkylating reaction, and asymmetrical Diels-Alder reaction.
