Reaction Steps
In a 500 ml flask as charged a 0.1 ML-1 dried THF solution containing 18 ml of lithium copper tetrachloride under a nitrogen atmosphere, followed by cooling to -50° C. The above prepared Grignard reagent was added thereto over 5 minutes, and the mixture was reacted at that temperature for 20 minutes. To the reaction mixture was added dropwise a solution of 8.07 g of (R)-glycidyl p-toluenesulfonate (produced by Aldrich Chemical Co., Inc.) in 70 ml of dried THF at the same temperature over 20 minutes through a dropping funnel, followed by further reacting for 1.5 hours. .The resulting reaction mixture was poured into a saturated ammonium chloride aqueous solution and extracted with diethyl ether. The extract was washed twice with a saturated sodium chloride aqueous solution, and the solvent was removed by distillation under reduced pressure to obtain 10.1 g (yield=95%) of a crude product.
