Reaction Steps

To a solution of 2,2-dimethyl-1,3-dioxane-4,6-dione (43.2 g, 300 mmol) and pyridine (47.5 g, 600 mmol) in 300 ml of CH2Cl2 was added hexanoyl chloride (40.4 g, 300 mmol) dropwise at 0° C. The mixture was stirred at 0° C. for 1 hr then at room temperature for 1 hr. The solution was washed with 1N aqueous HCl (300 ml), water (300 ml) and dried over Na2SO4. After evaporation of solvent, 5-hexanoyl-2,2-dimethyl-1,3-dioxane-4,6-dione was obtained as a light pink oil (35.4 g, 62%).
