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.

A very facile reaction between photochemically generated o-naphthoquinone methides (oNQMs) and thiols is employed for reversible light-directed surface derivatization and patterning. A thiol-functionalized glass slide is covered with an aqueous solution of a substrate conjugated to 3-(hydroxymethyl)-2-naphthol (NQMP). Subsequent irradiation...
