    • 8 (8.5 mg, 0.025 mmol), and TMTU (198 mg, 0.15 mmol) in dry benzene (10 mL) was vigorously stirred at 70°C under CO (supplied from a balloon) until the substrate was consumed. The reaction mixture was stirred at same temperature for 1 h. The resulting solution was passed through a small pad of silica gel using a mixed eluent of hexane and ethyl acetate (4/1, v/v). Purification of the crude products by flash chromatography on silica gel afforded pure bicyclic enone 2 (114 mg; 96%).
