Furan (214 ml, 3.15 mol) and magnesium iodide (7.0 g, 0.025 mol) are added to 2-(2,4,6-trimethylphenyl)cyclopent-4-ene-1,3-dione (27.0 g, 0.126 mol) and the mixture is stirred at room temperature for 4 days. The reaction mixture is concentrated under reduced pressure and the residue is purified by column chromatography on silica gel to give (1RS,2SR,6RS,7SR)-4-(2,4,6-trimethylphenyl)-10-oxatricyclo[5.2.1.02,6]dec-8-en-3,5-dione.
