Magnesium diiodide → (1RS,2SR,6RS,7RS)-4-(2,4,6-trimethylphenyl)-8-trimethylsilylethynyl-10-oxatricyclo-[5.2.1.02,6]decane-3,5-dione

Participants

Reaction Steps

3-(Trimethylsilylethynyl)furan (10.0 g, 61 mmol) and magnesium iodide (1.11 g, 4 mmol) are added to 2-(2,4,6-trimethylphenyl)cyclopent-4-ene-1,3-dione (4.34 g, 20 mmol) and the mixture is stirred at room temperature for 3 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,7RS)-4-(2,4,6-trimethylphenyl)-8-trimethylsilylethynyl-10-oxatricyclo-[5.2.1.02,6]decane-3,5-dione.
