実験手順
To a solution of the starting quinone from step 1 herein (56 mg; 0.22 mmol) in toluene (50 ml) was added 1-acetoxy-1,3-butadiene (30 μl; 11 eq). The mixture was stirred overnight at room temperature and was then concentrated and applied to a column of silica gel using 1-15% acetone in benzene to elute the product which was then recrystallized from dichloromethane:pentane affording the title compound as a yellow solid (10 mg; 15%).
