Catalytic Asymmetric Coupling of 2-Naphthols by Chiral Tridentate Oxovanadium(IV) Complexes

博士 === 國立臺灣師範大學 === 化學研究所 === 89 === A series of chiral oxovanadium(IV) complexes derived from tridentate N-3,5-substituted and N-3,4-benzo- and N-5,6-benzo-salicylidene-α-amino acids can serve as efficient catalysts for the enantioselective oxidative couplings of various 3-,6-,7-substituted- 2-naph...

We take the reseach about the solvent effect,cooxidant effect,amino acid effect….and so on in detail. Our catalyst in the coupling reaction of 2-naphthol is the best methodology as we know. The best scenario involves the use of a vanadyl complex arising from 2-hydroxy-1-naphtholaldehyde and valine (or phenylalanine) in CCl4, leading to BINOLs in good yields (75-100%) and with enantioselectivities of up to 68%.
