Experimental procedure: To a stirred solution of 1 (289 mg, 1.01 mmol), L-ethyl lactate (228 µL, 2.01 mmol) and triphenylphosphine (528 mg, 2.01 mmol) in benzene (3 mL) is slowly added diethyl azodicarboxylate (2.01 mmol) of at room temperature under argon. After 30 min the reaction mixture is concentrated in vacuo and the residue is purified by chromatography on silica gel (CH2Cl2 : hexanes) to give 2 (93% yield).
