Reaction Steps

5 g of 5,9-cyclododecadien-1,2-diol, 2.4 g of valeric aldehyde, a spatula of p-toluenesulfonic acid and 200 ml of 80/100 petroleum ether were charged into a 250 ml two-neck flask equipped with a water separator and the mixture was taken to reflux for 1 h. The reaction mixture was then poured on ice, neutralized with brine, dried and concentrated. Distillation in a bulb-to-bulb apparatus produced 6.06 g of 14-butyl-13,15-dioxabicyclo[10.3.0]pentadeca-4,8-diene.
