Procedure
In Example 2, 0.1 mL of a diethyl aluminum chloride/hexane solution was used in place of anhydrous aluminum chloride, and the color of the catalyst solution changed from brown to dark green by the addition of a diethyl aluminum chloride/hexane solution. Then 4-phenoxyphenol and propylene oxide were added to the dark green catalyst solution to achieve the reaction in the same manner as described in Example 2. Thus (S)-(+)-1-(4-phenoxyphenoxy)-2-propanol was obtained in 72% yield and the optical purity was 87% e.e.
