実験手順

To a solution of methyl-5,5-dimethyl-5,6-dihydro-naphthalen-8(7H)-one-2-carboxylate (Compound E2, 835.0 mg, 3.60 mmol) in 25.0 mL of THF at room temperature was added TiCl4 (670.0 mg, 3.55 mmol). Thereafter a solution of thiophenol (430.0 mg, 3.90 mmol) and Et3N (730.0 mg, 7.20 mmol) in 10 mL THF was added. The resulting brown mixture was stirred for 6 h before H2O was carefully added to quench the reaction. The pruduct was extracted into Et2O and the combined organic layers washed with saturated aqueous NaCl and dried over MgSO4. Removal of the solvents under reduced pressure afforded a solid from which the title compound was isolated as a yellow solid by column chromatography (5% EtOAc-hexanes).
