Oxyselenide → (E,E)-11,11-Diethoxy-2,6-dimethyl-10-oxo-2,6-undecadien-1-ol

Participants

Reaction Steps

In 70 ml of 95% ethanol was dissolved 7.4 g of 1,1-diethoxy-6,10-dimethyl-2-oxo-5,9-undecadien, and the resulting solution was, after addition of 1.7 g of selenium oxide, refluxed for 15 minutes. The ethanol was removed by evaporation, and the residue was, after addition of water, extracted with ether. The ethereal extract was washed with an aqueous sodium hydrogencarbonate solution and dried. The solvent was then removed by evaporation to leave an oil, and the oil was purified by the silica gel column chromatography to yield 3.0 g of the desired product.
