Bis(triphenylphosphine)palladium diacetate (20 mg, 0.024 mmol), 1-fluoro-3-iodo-benzene (104 mg, 0.47 mmol) and piperidine (0.16 ml, 1.6 mmol) are added to a solution of (1RS,2SR,6RS,7SR)-4-(2,4,6-trimethylphenyl)-10-oxatricyclo[5.2.1.02,6]dec-8-en-3,5-dione (0.20 g, 0.71 mmol) in dry N,N-dimethylformamide (2 ml). Formic acid (0.06 ml, 1.6 mmol) is added and the reaction mixture is heated at 50° C. for 2 hours. The reaction mixture is cooled to room temperature, water (1 ml) and dichloromethane (1 ml) are added, and the mixture is stirred for 1 hour. The two phases are separated, the organic phase collected and the solvent is evaporated. The residue is purified by preparative reverse-phase HPLC to give (1RS,2SR,6RS,7SR,8RS)-8-(3-fluorophenyl)-4-(2,4,6-trimethylphenyl)-10-oxatricyclo-[5.2.1.02,6]decane-3,5-dione.
