ethyl 2-chloro-3-cyclohexyl-3-oxopropanoate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of ethyl 3-cyclohexyl-3-oxopropanoate (1.0 g, 5.0 mmol) in diethyl ether (15 mL) was added sulfuryl chloride (750 mg, 5.5 mmol) at 0° C., and the mixture was stirred at room temperature for 1 hr. Saturated aqueous sodium bicarbonate solution (150 mL) and ethyl acetate (150 mL) were added to the reaction solution, and the mixture was stirred for 30 min. The organic layer was washed with saturated brine (10 mL) and dried over anhydrous magnesium sulfate, and the insoluble material was filtered off. The filtrate was concentrated under reduced pressure to give the title compound (870 mg, 60%) as a colorless oil. the mixture was stirred for 30 min The organic layer was washed with saturated brine (10 mL) dried over anhydrous magnesium sulfate the insoluble material was filtered off The filtrate was concentrated under reduced pressure
