應用

(R)-(+)-3,3′-Dibromo-1,1′-bi-2-naphthol reacts with zirconium(IV) tert-butoxide to form a chiral zirconium complex, which can efficiently catalyze:

anti-selective catalytic asymmetric aldol reactions of silyl enol ethers with aldehydes
asymmetric intramolecular [3+2] cycloaddition of hydrazone/olefins
