実験手順

261 mg of compound 10a was dissolved in 5 ml ethanol. A solution of 98 mg potassium cyanide in 5 ml water was added and the mixture was stirred at 35° C. for two days. 10 ml of a saturated aqueous sodium bicarbonate was added. The mixture was extracted twice with ethyl acetate. The combined extracts were dried with sodium sulfate and evaporated to give a yellow liquid. Purification with column chromatography (heptane/ethyl acetate 3/1) gave the title compound (38 mg) confirmed by NMR and LC/MS
