Water → (RS)-2-(2-buten-1-yl)-6-ethyl-1-indanone

Participants

Reaction Steps

A solution of 11.8 g of 6-ethyl-1-indanone, 15.4 ml of 3-buten-2-ol and 110 mg of p-toluenesulfonic acid in 110 ml of 2,2-dimethoxy-propane was boiled under reflux for 46 hours on a water separator filled with molecular sieve (0.4 nm, 2 mm pearl shaped). The reaction mixture was subsequently concentrated in a vacuum and purified by column chromatography on silica gel (hexane/diethyl ether 5:1). 7.92 g (50%) of (RS)-2-(2-buten-1-yl)-6-ethyl-1-indanone were obtained as a yellow oil.
