Reaction Steps

Step A A mixture of 2,2-dimethyl-propane-1,3-diol (Aldrich) (5 g, 48 mmol) in anhydrous ethyl ether (100 mL) at 0° C. was added thionyl chloride (8.7 mL, 120 mmol). The reaction mixture was stirred at 0° C. for 2 h. Water was added. The organic layer was separated, the aqueous layer was then extracted with ethyl ether. The combined organic layers were washed with saturated aqueous NaHCO3 solution, brine, dried over MgSO4, concentrated to give 5,5-dimethyl-[1,3,2]dioxathiane 2-oxide as a light pink oil (4.8 g, 82%).
