R. Irie et al., Asymmetric aerobic oxidative coupling of 2-naphthol derivatives catalyzed by photo-activated chiral (NO)Ru(II)-salen complex, SYNLETT, (10), 2000, pp. 1433-1436
Optically active 2,2'-binaphthol (BINOL) derivatives were synthesized with
moderate to good enantioselectivity via aerobic oxidative coupling of 2-nap
hthols using chiral (NO)Ru(II)salen complex 1 as a catalyst under irradiati
on of visible light.
