الإجراء التجريبي
A solution of 0.87 g (2.6 mmole) of diethyl-2-(SR)-phenyl-3-(SR)-hydroxy-(SR)-cyclohexylmalonate in 12 mL of THF and 7 mL of water was treated with 3.1 mL (7.8 mmole) of 10% aqueous sodium hydroxide and the mixture was heated in an oil bath at 70° C. under nitrogen for 24 hr. The mixture was cooled, 10 mL of water was added and the pH was adjusted to 2 with 2N aqueous HCl. The mixture was extracted with 3×35 mL of ethyl acetate, and the organic layer was dried with magnesium sulfate, filtered and concentrated in vacuo to give 700 mg of a light yellow foam. This material was carried on in Step F below.
