    • Typical reaction procedure for oxidation of 4-arylphenols 1: Compound 3 (0.050 mmol) was added to a solution of 1 (1.0 mmol) in THF-water (1:5, 6 ml), followed by Oxone® (4 mmol) at room temperature. After 1 was completely consumed, as indicated by TLC, the mixture was diluted with ethyl acetate and washed with water. The organic layer was then washed with aqueous saturated sodium bicarbonate solution and dried, concentrated. The residue was purified by column chromatography on silica gel to give pure 2. The alkaline solution was acidified by 10% hydrochloric acid solution and extracted with ethyl acetate. The organic layer was dried and concentrated to give recovered 3, which can be used after recrystallization from diethyl etherhexane. All new compounds gave satisfactory spectrospecific data
