実験手順
To a solution of (1RS,2RS,6SR,7SR)-4-(2,6-diethyl-4-methylphenyl)-5-methoxy-10-oxa-tricyclo[5.2.1.02,6]deca-4,8-dien-3-one (0.052 g, 0.16 mmol) in methanol (10 ml) is added 5% palladium on carbon (10 mg). The reaction is stirred under an atmosphere of hydrogen for 90 minutes. The reaction is filtered through diatomaceous earth and the filter pad is washed with ethyl acetate (10 ml). The solvent is removed under reduced pressure to yield (1RS,2RS,6-SR,7SR)-4-(2,6-diethyl-4-methylphenyl)-5-methoxy-10-oxa-tricyclo[5.2.1.02,6]dec-4-en-3-one.
