실험 절차

To a solution of phenyl cyclohexene (79 mg, 0.5 mmol) in a mixture of acetonitrile (4.5 ml) and water (2 drops) were added first finely crushed NaHCO3 (168 mg, 2 mmol) and oxone (307 mg, 0.5 mmol) then the catalyst (0.05 mmol). The resulting yellow suspension was allowed to react at RT, under good stirring. TLC was used to follow the reaction which indicated that the reaction was finished in 2 h. Water (3 ml) was added to the reaction mixture followed by extraction into methylene dichloride. The organic extracts were combined and dried over anhydrous sodium sulphate. Concentration on a rotary evaporator gave a material which was purified on a column using 2% ethyl acetate:petrol mixture as eluent to give the desired compound as a colourless oil. (72 mg, 83% yield, 70% e.e).
