英文摘要The chiral bimetallic oxovanadium complexes have been designed for the enantioselective oxidative coupling of 2-naphthols bearing various substituents at c6 and/or c7. the chirality transferring from the amino acid to the axis of the biphenyl in oxovanadium complexes 2 was found to occur with the use of uv and cid spectra and dft calculation. the homo-coupling reaction with oxygen as the oxidant was promoted by 5 mol % of an oxovanadium complex derived from l-isoleucine and achiral biphenol to afford binaphthols in nearly quantitative yields with high enantioselectivities of up to 98% ee. an oxovanadium complex derived from l-isoleucine and h-8-binaphthol is highly efficient at catalyzing the air-oxidized coupling of 2-naphthols with excellent enantioselectivities of up to 97% ee. v-51 nmr study shows that the oxovanadium complexes have two vanadium(v) species. kinetic studies, the cross-coupling reaction, and hrms spectral studies on the reaction have been carried out and illustrate that two vanadium(v) species are both involved in catalysis and that the coupling reaction undergoes a radical-radical mechanism in an intramolecular manner. quantum mechanical calculations rationalize the importance of the cooperative effects of the axial chirality matching s-amino acids on the stereocontrol of the oxidative coupling reaction. the application of the transformation in the preparation of chiral ligands and conjugated polymers confirms the importance of the current process in organic synthesis.
