(E)-4-oxonon-2-enal

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2.0 g (14.47 mmol) of 2-pentylfuran was dissolved in 60 ml of dichloromethane, and 3.84 g (14.47 mmol) of 65% m-chloroperbenzoic acid was added dropwise thereto with stirring under ice-cooling, followed by stirring for 1 hour at the same temperature. To the reaction solution was added saturated aqueous sodium carbonate and the mixture was extracted with dichloromethane. The organic layer was washed with water, dried over anhydrous magnesium sulfate, and was then concentrated under reduced pressure to give 1.62 g of the title compound as a yellow oil (yield: 73%). cooling by stirring for 1 hour at the same temperature the mixture was extracted with dichloromethane The organic layer was washed with water dried over anhydrous magnesium sulfate was then concentrated under reduced pressure
