Catalytic oxidative coupling of 7-Alkoxy-l-naphthols by chiral vanadium complexes

3 CATALYTIC OXIDATIVE COUPLING OF 7-ALKOXY-l-NAPHTHOLS BY CHIRAL VANADIUM COMPLEXES 

To a solution of chiral vanadium catalyst (892.5 mg, 1.45 mmol) in CCU (100 mL) was added 7-allyloxy-2-naphthol (5.0 g, 25 mmol). The resulting 

Note This procedure has been scaled up to provide 50 g of the optically pure 7,7 -diallyloxy-2,2 -dihydroxy-1,1 -binaphthyl.
