Reaktionsschritte

To a solution of 1.1 g (3.09 mmol) of 1-(3,6-dimethoxy-2,4,5-trimethylphenyl)-1-(3-pyridyl)heptane in 20 ml of acetonitrile-water (1:1), the solution of 4.5 g (8.2 mmol) of cerium ammonium nitrate (CAN) in 15 ml of acetonitrile-water was added dropwise with stirring at 0° C. and stirred for 30 minutes after the completion of addition. The reaction product was isolated by a routine method, to give 635 mg (63%) of 1-(3,5,6-trimethyl-1,4-benzoquinon-2-yl)-1-(3-pyridyl)heptane. The physical data are shown in Table 2-1.
