실험 절차

To a solution of 5.6 g of tricyclo[6.2.2.02,7]dodeca-2,4,6-trien-9-ol in 30 mL of DCM were added 110 mL of a 15% DMP solution in DCM. After stirring overnight 300 mL of EtOAc/Hept (1:1) were added, the obtained suspension was filtered over a pad of celite and the filtrated was concentrated in vacuo. The residue was treated again with EtOAc/Hept (1:1) and filtered over celite. This procedure was repeated twice to obtain 4.9 g of the desired compound as yellow oil.
