반응 단계
152 g of 1-methoxybutan-3-one is dripped in the course of one hour into a boiling mixture of 400 g of diethyl ketone and 5 g of a 30% by weight solution of sodium methylate in methanol. The whole is then heated under reflux for another hour. The reaction mixture is neutralized with glacial acetic acid and then fractionated. 70 g of 2,3,6-trimethyl-2-cyclohexen-1-one and 9 g of 4-methyl-3-ethyl-2-cyclohexen-1-one is obtained. The total yield of cyclohexenone is 57% with reference to 1-methoxybutan-3-one.
