実験手順
A mixture of 3,3'-dihydroxydeoxybenzoin (0.05 mol), ethyl bromoacetate (0.05 mol) ad K2CO3 (0.05 mol) in 50 mL of DMF is stirred at room temperature overnight. The reaction mixture is poured into water and extracted with EtOAc. The organic solution is dried and evaporated to dryness. The crude products are separtated by flash chromatography to give the ethyl 2-(3-(2-(3-hydroxyphenyl)-2-oxoethyl)phenoxy)acetate and the ethyl 2-(3-(2-(3-hydroxyphenyl)-1-oxoethyl)phenoxy)acetate.
