General procedure: To a solution of 1 mmol of thiol in acetonitrile (2mL), was added a solution of 8 mL of phosphate buffer including laccase (40 U) and 4-phenyl urazole (10 mol%). The resulting mixture was stirred under air at room temperature for the time specified. After completion of the reaction (monitored by TLC), NaOH (10%, 10 mL). The combined organic phases were dried over anhydrous Na2SO4, filtered and evaporated under reduced pressure. The crude products were purified by recrystallization or chromatography on silica gel (n-hexane/EtOAc, 5/1). All the products were known and characterized by comparison of their spectral data (1H NMR) and physical properties (melting point) with those of authentic samples., 2382-96-9
