Reaktionsschritte
Following a modified procedure by Tremblay et al.,17 2,3,4-trimethoxybenzaldehyde (16, 6.075 g, 31.0 mmol) was dissolved in MeOH (60.0 mL), and then H2SO4 (0.6 mL) and 35% aq. H2O2 (4.0 mL, ˜40 mmol) was added at room temperature. The reaction was then heated to reflux for 2 hrs and monitored by TLC (1:4 EtOAc:hexanes) for completion. When the reaction was complete the solution was cooled and extracted with ethyl acetate. The layers are separated and the organic layer was washed with brine, dried over MgSO4, and filtered. Flash chromatography (1:4 EtOAc:hexanes) provides 17 (5.564 g, 30.2 mmol, 98%) as a light red oil.
