Reaction Steps

To a cooled (−78° C.), stirred solution of 2,2-dimethyl-4,7-dimethoxy-indan-1-one (1 g) in dichloromethane (20 mL) was added boron trichloride (9 mL of a 1M solution in dichloromethane) over a 5 min period. The reaction was allowed to warm to RT, stirred for 3 h, then recooled to −78° C., quenched with ice, allowed to warm to RT and stirred for 1 h. The reaction was extracted with dichloromethane, the organic layers dried over sodium sulfate, concentrated in vacuo and flash chromatographed to afford 2,2-dimethyl-7-hydroxy-4-methoxyindan-1-one (0.85 g) as a tan oil.
