実験手順: A solution of 8.70 g (63 mmol) of 1,3-dimethoxybenzene in 164 mL of anhydrous tetrahydrofuran was stirred at -20° C. while 1.6M n-butyllithium in hexane (42.1 mL; 67.2 mmol) was added dropwise, over 20 min. The solution was stirred at -20° C. for 3 hr and then allowed to warm to -5° C. whereupon 15.66 g (63.6 mmol) of 1-iodo-3-phenylpropane was added over 15 min. The reaction mixture was stirred at -5° C. for 1 hr and then at room temperature for 3 d. After being recooled to -5° C., the reaction mixture was decomposed by the addition of 1.5N aqueous sulfuric acid. Water was added and the mixture was worked-up with ether in the usual manner. The residue was treated with 100 mL of hexane and the mixture was filtered. Removal of the solvent in vacuo gave 15.28 g (94.7%) of the title compound as a yellow oil. was added dropwise, over 20 min was added over 15 min The reaction mixture was stirred at -5° C. for 1 hr at room temperature for 3 d After being recooled to -5° C. the mixture was filtered Removal of the solvent in vacuo

実験手順: A mixture of pentane-2,4-dione (3.87 g, 38.6 mmol), 3-phenyl-1-iodopropane (3.18 g, 12.9 mmol) and anhydrous potassium carbonate (1.7 g, 12.3 mmol) in acetone (7.5 mL) was heated to reflux for 24 hours. The room temperature reaction mixture was filtered, and the filter cake washed with acetone (25 mL×3). The combined filtrates were concentrated, and the residue was partitioned between ethyl acetate and water. The organic layer was washed with water and brine, dried (magnesium sulfate), and concentrated to an oil. Flash chromatography over silica (ethyl acetate/hexanes) afforded 1.13 g (42%) of a colorless oil. The proton spectrum in deuterochloroform showed the product exists as a mixture of keto and enol tautomers. was heated to reflux for 24 hours The room temperature reaction mixture was filtered the filter cake washed with acetone (25 mL×3) The combined filtrates were concentrated the residue was partitioned between ethyl acetate and water The organic layer was washed with water and brine dried (magnesium sulfate) concentrated to an oil
