Reaction Conditions

Reaction Steps

7-formyl-4-isopropyl-2-hydroxy-2,4,6-cycloheptatrien-1-one (2.00 g, 10 mmol) was dissolved in tetrahydrofuran (20 ml) and cooled to -78° C. in a dry ice/acetone bath. A solution of methyllithium the ether (1.4M, 15 ml) was added dropwise to the solution, then dry ice/acetone bath was removed and stirring was continued until the insolubles were dissolved. An aqueous saturated ammonium chloride was added to the reaction mixture and extracted with methylene chloride. The methylene chloride layer was washed with water, dried over anhydrous sodium sulfate and solvent was distilled off to give 2.18 g of 7-(α-hydroxyethyl)-4-isopropyl-2-hydroxy-2,4,6-cycloheptatrien-l-one as a reddish brown oil (yield: quantitative).
