Procedure

The alcohol compound (4.85 g, 13.7 mmol) prepared as above was dissolved in methylene chloride and the mixture was oxidized with active manganese dioxide (14.6 g) at room temperature for 2 hours. Working up in usual way gave 2,3-dimethoxy-5-methyl-1,4-bismethoxymethyloxy-6-(4-formyl-1,3-butadienyl)benzene [oily substance, δ 2.30 (3H), 3.49 (3H), 3.58 (3H), 3.86 (3H), 3.89 (3H), 5.06 (4H), 6.23 (1H), 7.0-7.4 (3H), 9.65 (1H)]. Yield 93%.
