実験手順

A mixture of 3 (200 mg, 0.57 mmol), benzenesulfonyl chloride (109 μL, 0.85 mmol), n-BuNHSO4 (25 mg, 0.074 mmol) and 50% aqueous NaOH (108 μL) in CH2Cl2 (3.5 mL) were stirred for 0.5 h. The mixture was partitioned between sat. aq. NaHCO3/CH2Cl2. The organic layer was separated and the aqueous phase extracted with CH2Cl2. The combined organic solutions were dried (MgSO4) and concentrated to give 4 as an orange oil (336 mg, 120
