반응 단계
A solution of 12.1 g of 6-methoxy-3.3-dimethyl-1-indanone, 11.1 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 67 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 4:1). In addition to 4.64 g of educt, there were obtained 5.86 g (38%) of (RS)-2-(2-buten-1-yl)-6-methoxy-3,3-dimethyl-1-indanone as a yellow oil.
