実験手順
Furfuryl alcohol (4 ml, 46.7 mmol) is added to 2-(2,4,6-trimethylphenyl)cyclopent-4-ene-1,3-dione (2.0 g, 9.3 mmol) and MgI2 (520 mg, 1.86 mmol) and the reaction is stirred for 17 hours. The reaction mixture is adsorbed onto silica gel and purified by column chromatography on silica gel to give (1RS,2SR,6RS,7SR)-1-hydroxymethyl-4-(2,4,6-trimethylphenyl)-10-oxatricyclo-[5.2.1.02,6]dec-8-ene-3,5-dione.
