Reaction Steps

Potassium cyanide (0.12 g, 1.8 mmol) was added to a mixture of 5-cyclobutylidene-2,2-dimethyl-1,3-dioxane-4,6-dione (0.30 g, 1.5 mmol) and tetra-N-butylammonium bromide (0.049 g, 0.15 mmol) (Sigma-Aldrich, Cat. #193119) in ethanol (5.0 mL). The reaction mixture was stirred at 80° C. for 2 h. After cooled to r.t., the mixture was adjusted to pH=2 with aqueous HCl. The mixture was extracted with ethyl acetate (3×20 mL). The combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column with ethyl acetate in dichloromethane (0-80%) to afford the desired product (0.32 g, 94%).
