Participants

Reaction Steps

To a slurry of 2-(2-Hydroxy-5-oxo-5,6,7,8-tetrahydro-naphthalen-1-ylmethyl)-isoindole-1,3-dione (862 mg, 2.68 mmol) in THF (17 mL) was added ®-2-imidazol-1-yl-1-phenyl-ethanol (606 mg, 3.22 mmol) and triphenylphospine (846 mg, 3.22 mmol). After 15 min, diethylazodicarboxylate (0.51 mL, 3.22 mmol) was added and the reaction became homogenous. The reaction was stirred for 2 days and concentrated to give a reddish-brown foam. Purification by chromatography (10-20% acetone/CH2Cl2 then 5% MeOH/CH2Cl2) afforded the title compound as a light brown foam (1.15 g, 2.35 mmol, 87%). The structure was confirmed by NMR and mass spectrometry. MS m/z 492 (M++H).
