A new, rapid, and sensitive method for assaying phenol sulfotransferase activity toward 2-naphthol is described. The product 2-naphthyl sulfate is quantitated fluorometrically. Optimal wavelengths for excitation and emission were determined by recording the three-dimensional fluorescence spectra of the substrate and...

Iron(salan) complex 1 was found to catalyze the oxidative dearomatization of 1-substituted 2-naphthols with the formation of an all-carbon quaternary stereocenter in air in the presence of nitroalkanes, to afford the corresponding cyclic enones with high enantioselectivity of 88-96% ee.

With in situ molecular imprinting technique, a novel nanoelectrode (MI, n-P)-TiO(2) with n-P heterojunction and molecular recognition ability was fabricated by liquid phase deposition at low temperature. Using bisphenol A (BPA) as template, the spindle-like TiO(2) particles 40-80 nm in...

An efficient water soluble fluorescent Al(3+) receptor, 1-[[(2-furanylmethyl)imino]methyl]-2-naphthol (1-H) was synthesized and characterized by physico-chemical and spectroscopic tools along with single crystal X-ray crystallography. High selectivity and affinity of 1-H towards Al(3+) in HEPES buffer (DMSO/water: 1/100) of pH 7.4...

The first enantioselective total synthesis of the bisanthraquinone (S)-bisoranjidiol and an unnatural regioisomer has been accomplished. Key features of the synthesis include the asymmetric oxidative biaryl coupling of a hindered 8-substituted 2-naphthol, selective para-quinone formation, and regioselective tandem Diels-Alder/aromatization reactions.
