OCTAHYDRO-1H-CYCLOBUTA[CD]PENTALEN-1-ONE

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Into 0.5 ml of ethanol was dissolved tricyclo[4,2,1,03,9]nonane-2-one (13.6 mg, 0.1 mmol). Into this ethanol solution was added the Co (III) (salen) complex (3.7 mg, 5 μmol) having the above formula (XI). Into this solution was added 30% hydrogen peroxide aqueous solution (15 μI, hydrogen peroxide content 0.13 mmol), which was stirred at room temperature for 24 hours. After the completion of the reaction, the mixed liquid was concentrated, and the residue was chromatographed in a silica gel column with hexane/ethyl acetate (=8/2) as a developing solvent, thereby obtaining 2-oxatricyclo[5.2.1.04,10]decane-3-one (4.7 mg, yield 31%) having the above formula (VIII). The enantiomer excess percentage of the product was determined as follows. After the completion of the reaction the mixed liquid was concentrated the residue was chromatographed in a silica gel column with hexane/ethyl acetate (=8/2) as a developing solvent
