Potassium Hydroxide → HCID 13071115, compound

Participants

Reaction Steps

7-Methylsulphonyloxy-3-methylsulphonyloxymethyl-2,4-dioxabicyclo[3,3,1]nonane (280 mg) is added to 5 ml of a boiling 2n potassium hydroxide solution in absolute alcohol and the mixture is boiled for 2 minutes under reflux while stirring vigorously. The reaction mixture which has congealed to a crystalline solid is cooled and, after treatment with 5 ml of 8% sodium bicarbonate solution, extracted three times with methylene chloride. The combined extracts are dried with sodium sulphate and the solvent is distilled off under reduced pressure to leave as residue the crystalline racemic 3-methylsulphonyloxymethyl-2,4-dioxabicyclo[3,3,1]non-6-ene (m.p. 53°-56°).
