Reaction Steps

Diethyl azodicarboxylate (2.31 ml, 14.7 mmol) is slowly added to a solution of (R)-(+)-α-hydroxy-γ-butyrolactone (1 g, 9.8 mmol), 4-trifluoromethylphenol (1.58 g, 9.8 mmol) and triphenylphosphine (3.86 g, 14.7 mmol) in anhydrous THF (80 ml) cooled to 0° C. After stirring for 5 minutes at 0° C. and overnight at room temperature, the solvent is evaporated off and the triphenylphosphine oxide is then precipitated from ether and filtered off. The filtrate is then washed with water, dried over magnesium sulphate and evaporated. After purification by flash chromatography (3/1 heptane/EtOAc), the expected compound is obtained in the form of a white powder (1.14 g, 47%).
